In the south-western corner of South Africa, the Cape Floristic Region boasts a unique ecosystem that is renowned for its remarkable biodiversity. At the heart of this vibrant botanical haven lies the Fynbos biome, a floral kingdom that, over millions of years, has evolved into one of the most diverse and ecologically significant places on our planet.

Despite the challenging conditions of this region, more than 9,000 plant species flourish in this unique ecosystem, from shrubs and heathers to bulbs and reeds. Many of these are endemic species, and some showcase truly unique adaptations.

What is the Fynbos?

The term ‘fynbos,’ meaning ‘fine bush,’ refers to the distinctive plant life found in the southern tip of Africa. This region encompasses various species that thrive in nutrient-poor soils derived from quartzitic limestone and sandstone. The shrub and heathland areas boast a Mediterranean climate and impoverished soil. Despite the challenging conditions, over 9,000 species thrive in this unique ecosystem.

Because of the sheer number of species here, fynbos is considered to be one of the most biodiverse places on earth. The area stretches from the coast of the Western Cape of South Africa all the way to the mountains. It covers an area of around 34,747 mi² (90,000 km²) but is still the smallest floral kingdom in the world. However, it does have the richest diversity.

Being an iconic part of southern Africa, it’s no wonder that fynbos is of cultural importance to the native people here. In fact, the plants have been used for their medical properties by the San People for many thousands of years.

Regions

Fynbos is divided into several regions, including the Cape Peninsula where you’ll find Table Mountain. It’s here that there is a variety of microclimates due to the varying altitudes which makes it incredibly diverse in terms of flora.

To the east of the peninsula we find Overberg which contains both fynbos and renosterveld landscapes (more on that later). Here you’ll find the Agulhas Plain which is one of the most biodiverse areas on the planet.

Alongside the peninsula are the Cape Flats, and while this has been largely urbanized, conservation focus here is of the utmost importance. The Cederberg Mountains are another region of the fynbos and contain many rare species. The Boland Mountains are also a fynbos biodiversity hotspot and are home to many higher-altitude species.

Moving down to the southern coast of South Africa, we find the Garden Route which has many beautiful coastal species and, as such, is very popular with tourists.

Other important fynbos regions include Baavianskloof which, while being something of a wilderness, still contains an impressive number of flora species. There’s also the Kogelberg Biosphere Reserve which is a UNESCO site and plays an important role in conserving endemic species.

Vegetation Types

Around 70% of all fynbos plants are endemic to the area, and there are several different types, including heathers, proteas, and grass-like restios. However, it’s important to keep in mind that there are two main vegetation types; fynbos and renosterveld.

Where fynbos plants grow in nutrient-poor soil, renosterveld plants are found in much richer soil. Surprisingly, despite the poor growing conditions, fynbos has far greater biodiversity than renosterveld. However, Renosterveld used to be home to many large animals which simply wouldn’t be able to survive in fynbos owing to the low quality soil that would be unable to sustain game.

The very word renosterveld can be translated to mean ‘rhinoceros field’, which is in reference to the thousand of these animals that once lived here. 

The soil in fynbos is much more sandy and acidic, while the renosterveld soils are clay-rich and fertile.

Fynbos Flora Adaptations

Now that we understand the poor growing conditions of the fynbos, it would be difficult to believe that plants could grow here. But these amazing species have several adaptations that allow them to thrive.

Adaptations to Fire

Fynbos is exposed to regular wildfires, but the plants here are used to this. In fact, there are some that even need fire in order to reproduce and have seeds that will only germinate when exposed to heat or smoke.

One such example is the fire lily (Cyrtanthus ventricosus) that only flowers after being stimulated by the smoke from wildfires. This means that it doesn’t flower every year but when it does, it doesn’t face competition and blooms with stunning tubular red flowers.

Plants like this have structures called serotinous cones, which will only open when exposed to high temperatures. 

Amazingly, the wildfires here help to shape the landscape. When they occur, they’re much cooler than forest fires and are responsible for pruning plants like proteas and activating seed pods. The ash that falls into the soil even acts as nourishment for plant seeds. In the first year after a fire (which can occur every 10 to 15 years), plants tend to grow much more quickly owing to the reduced competition and high levels of nutrients in the soil

In fact, some plants here actually rely on fire to complete their lifecycles. They’re then able to rapidly spread across the landscape once again.

Other adaptations include thick bark, which insulates the plant as well as the ability to grow in rocky crevices which further protects the plant.

Proteoid Roots

Plants within the protea family have specially adapted roots which give them a much larger surface area and allow them better reach to search for nutrients in the poor quality soil. These roots typically grow in clusters of thin rootlets known as cluster roots or proteoid roots. Not only do they provide the plant with greater reach, but it’s also thought that they may chemically modify the soil to improve nutrient uptake.

They do this by releasing organic acids that break down nutrients within the soil, such as iron, phosphorus, and aluminum. 

Scientists have also found the thinnest roots in the world in fynbos which are designed to outcompete non-native species for resources in the low nutrient soil.

Other fynbos plants, such as Erica mammosa, form a relationship with mycorrhizal fungi which again aids them in nutrient uptake owing to the fungi’s ability to cycle nutrients, like phosphorus, within the soil.

Sclerophyllous Leaves

Conditions in fynbos can be very hot and dry, so it’s important for plants to be able to retain water. For this reason, many species of protea have adapted small, leathery leaves with a thick skin to reduce evaporation and transpiration.

The size of these sclerophyllous leaves means a smaller surface area, and you’ll also notice that they’re situated close together on the stem. This helps to protect the plant from the dry winds. 

What’s more, since they have a glossy texture, this helps to reflect sunlight as opposed to absorbing it, further reducing water loss.

These leaves are usually covered in small hairs or spikes and is something that’s often seen in plants that grow in low-quality soils. These hairs secrete oil and tannins which adds a further layer or evaporative protection but also helps to deter animals from feeding on them. Furthermore, the tannins slow down decomposition. When this process is slower, more nitrogen is produced, which then enters the soil, enriching it for future growth.

Unique Pollination Strategies

Fynbos is unable to sustain much fauna, but there are some species here, including six endemic bird species, some of which help to pollinate the unique flora here. 

One such species is the cape sugarbird, a keystone species of fynbos, which can visit as many as 300 flowers in a single day. These birds, like many other nectar-feeders, have long, pointed beaks to extract nectar from the tubular shaped flowers often found in fynbos.

However, each flower has its own type of pollinator and is specifically adapted to attract it. This may include bright colors, light reflecting petals, and specific flower sizes to attract insects like beetles, butterflies, and bees. In Overberg renosterveld, solitary bees from the Melittidae family are some of the most important specialist pollinators. Certain species of Erica have very specific scents and colors to attract nocturnal pollinators like the hawkmoth. 

Where insects are concerned, there are some plants that will even trap the pollinator inside until it collects or deposits pollen.

Some flowers like pincushion proteas have specially adapted seed heads that are designed only to be pollinated by rodents, like mice, but have modified leaves that birds cannot penetrate.

Examples of Fynbos Flora

The biodiversity of fynbos rivals that of the tropical rainforests and there are thousands of plant species living here. These include those from families like Protaeceae, Ericaceae and Restionaceae which are dominant members of this landscape.

While I cannot provide an exhaustive list of every plant, I’d like to discuss some of the most interesting species.

1. True Protea (Sugarbush)

One of the most iconic fynbos plants is the true protea, commonly known as the sugarbush, and there are around 360 different species, each with its own characteristics. Some even have adaptations to release seeds when exposed to fire.

Perhaps one of the most unique types of South African flora, sugarbushes are among the most colorful. Their unique appearance with large bracts around the flowers and a rich nectar source is what sets them apart. Their structure also makes them specially adapted for bird pollination.

True proteas are South Africa’s national flower, and many species are endemic to the region. Because of their beauty, they’re often found in cut flower arrangements.

Common Sugarbush (Protea repens)

The common sugarbush is endemic to the southwestern Cape of South Africa and grows incredibly well in the fynbos, particularly in sandy, well-draining soils. These areas are prone to wildfires, but this species is specially adapted to survive, with its seed cones only opening when stimulated by fire. What’s more, seeds are often stored underground by ants, allowing the plant to regrow after a fire.

These dense, erect shrubs grow up to 13 feet (4 meters) and produce blooms in a range of colors from red to white. The leaves are stiff and leathery, which not only prevents water loss but stops insects from feeding on the plant.

Flowers bloom in the dry season but persist through winter and are pollinated by nectar-loving birds like the sunbird as well as insects like the Cape honeybee.

King Protea (Protea cynaroides)

The King protea is so called because of its large flower heads which are the largest within the protea family.  It grows in sandy soils up to an altitude of 3,773 feet (1,500 meters).

Each plant typically produces up to 4 flower heads per season, and each flower head can range between white and red and contains several small flowers surrounded by bracts. However, pale pink is the most iconic and often used in floral displays. Horticulturists have actually developed 81 king protea varieties.

These are woody shrubs that benefit from thick, glossy leaves which reflect sunlight and are unattractive to insects. So iconic are they that this species is considered the official flower of South Africa.

As with the sugarbush, king protea is pollinated by nectar-feeding birds like the sunbird and the sugarbird. The seeds are dispersed by the wind and in the event of a fire, underground seed-containing buds ensure new growth.

2. Leucospermum (Pincushions)

Leucospermum, more commonly known as pincushions, are well loved for their brightly colored, brush-like flower clusters that look like pincushions, which is where they get their name. Within this family, there are 48 known species, and each is specially adapted to attract its own pollinators which include birds and insects.

Rich in nectar, pincushions are very attractive to sunbirds, and these beautiful birds help to pollinate the plants.

In terms of seed production, pincushions will release their seeds when exposed to fire. This element also encourages germination, meaning they’ll begin to grow after a wildfire.

Pincushion Protea (Leucospermum cordifolium)

The pincushion protea is a large plant that can grow up to 5 feet (1.5 meters) and boasts globe-shaped flower heads that can measure up to 4.7 inches (12 cm) in diameter. Flowers typically appear between July and November and are pollinated by birds and scarab beetles as well as mice, thanks to the flowers being close to the ground. 

Once the fruits fall to the ground, ants will collect the seeds and store them underground ready for germination in the event of a wildfire. Amazingly, the plant produces nectar early in the morning to attract insects which in turn attract birds.

This species is popular in South Africa as a garden plant as well as for cut flowers and is also cultivated in nurseries as far north as Egypt. However, it is endemic to South Africa and the acidic soils of fynbos.

Gray Tree Pincushion (Leucospermum conocarpodendron)

The gray tree pincushion is the largest species within its genus and can grow as tall as 20 feet (6 meters) in height!

This species produces large, yellow flower heads that grow up to 3.5 inches (9 cm) and have a showy appearance. They typically grow enclosed by the toothed leaves in groups of around three.

The seeds of the gray tree pincushion are often stored underground and can remain intact for anywhere between 80 and 200 years. Seed dispersal typically occurs as a result of a symbiotic relationship with ants who feed on the fruits but leave the hard seeds underground. When wildfires blaze, the extreme heat causes the seeds to germinate.

Adult plants are easily able to survive fires thanks to their thick bark. Being so tall also helps them to resist the effects of the blaze.

The flowers are pollinated primarily by nectar birds like the sugarbird and sunbird. However, cross pollination is a problem, and conservationists worry that if this continues, the gene pool will be so contaminated that the plant dies out.

3. Leucadendron (Cone Bushes)

There are around 80 species of Leucadendron, and they’re well-loved as garden plants thanks to their colorful appearance. As their common name suggests, the inflorescences are cone-shaped and contain seeds that are released during a wildfire event. What’s more, the seeds are incredibly resistant and easily able to survive the heat and smoke of a fire.

Cone Bushes are evergreen shrubs native to South Africa, but they were introduced to New Zealand back in the 60s. They’re resistant to drought and easy to care for, which is another reason they’re often seen in domestic gardens.

Lots of conebush species rely on bird pollination, but some are also adapted to attract insect pollinators.

Golden Cone-Bush (Leucadendron laureolum)

The golden cone-bush is endemic to the southwestern Cape of South Africa and grows in a range of soil types from a single stem but has a wide spread and can reach heights of 6.6 feet (2 meters). These evergreen shrubs are a popular garden plant owing to their changing winter colors from green to yellow.

Golden cone bushes can grow at altitudes of up to 3,280 feet (1,000 meters) and flower between June and August when they produce yellow flower heads, although the male plants are much more vibrant than the females. Interestingly, after pollination by insects (typically beetles), the male flowers fade and fall off. However, the female flowers take on a greenish-yellow appearance and a more woody texture, remaining on the plant for years.

These hardened structures contain seeds which are only released during a wildfire. Once this happens, the parent plant finally dies.

Silver Tree (Leucadendron argenteum)

Found only in a small area of the Cape Peninsula, the silver tree is a short lived species (around 20 years) that can grow as tall as 23 feet (7 meters), making it one of the more majestic flora in fynbos.

The seeds of the silver tree will only germinate during a fire and this is an important part of its lifecycle, with almost half the population dying out in fires in the mid-2000s, but fully recovering shortly thereafter.

Often seen growing on the side of mountains, Leucadendron argenteum has a silvery appearance thanks to the leaves which are adapted to reflect light and reduce the risk of water loss. The leaves are also covered in tiny hairs which are what create the silver tone. This tree also protects itself from elements like fire with thick gray bark.

4. Erica (Heaths)

Erica is a genus that contains as many as 857 species of plants, more commonly known as heaths. These plants, depending on their species, can be found in a variety of fynbos habitats from mountains to lowlands.

These plants are typically shrubs that don’t grow very tall, although there are exceptions like the tree heath, which can grow to 23 feet (7 meters). Most species produce tubular-shaped nectar-containing flowers that serve to attract sunbirds for pollination. But the flowers also add aesthetic value to fynbos thanks to their often bright colors and clustered blooms.

More often than not, Erica plants thrive in well-draining soils and are frequently one of the more dominant species within an area. With thin leaves that reduce evaporation and transpiration, these plants can survive in arid conditions and are built to withstand wildfires. What’s more, they rely on fire for reproduction.

White Heath (Erica sessiliflora)

Sometimes called the green heath, this species is considered to be one of the most beautiful within the cape. It boasts long green tubular flowers that are seemingly stemless. However, at the base of the flower is the sessile (which inspired the scientific name), which contains a seed and hardens over time.

Seed pods develop each year so individual white heaths may end up with several growing on top of one another. It’s not until they are stimulated by the smoke from a wildfire that the cones pop open, and the seeds fall to the ground where they germinate. This is a unique trait of this particular species.

The tubular flowers are special adaptations that allow sunbirds to use their long bills to extract nectar, and they’re one of the white heath’s primary pollinators. Because of the plant’s unique appearance, it’s often used as a garden plant and prefers to grow in slightly moist soil.

5. Restio (Restios)

Restios more commonly known as cape reed, feature slender stems that stand upright, giving them a grass-like appearance. Typically, they grow in dense clusters, and there are more than 570 known species. 

Native to the Cape Floristic Region in South Africa, restios can be found growing in various habitats and soil types. Owing to the challenging conditions in fynbos, each species has specially adapted in order to survive here with things like fire adaptations, traits that attract certain pollinators, and underground seed storage.

While some cape reeds do rely on insect or bird pollination, a large number are wind pollinated because, unlike other fynbos plants, they aren’t as showy and attractive.

Cape Thatching Reed (Elegia tectorum)

The Cape thatching reed, as its name suggests, has been used by humans for centuries for thatching as well as crafts like basket making. Today, it’s a popular garden plant and a common sight in fynbos.

These perennial plants typically grow to around 4.9 feet (1.5 meters) in height and have a tufted appearance with tiny 0.12 inches (3mm) flowers in a golden-brown color. Male flowers act as a pollen source for bees but it’s not these insects that pollinate them, rather the wind.

Cape thatching reeds grow in shallow water, typically around streams and ponds and are a common feature in domestic gardens owing to their bold shape.

6. Agathosma (Buchu)

One of the most distinct characteristics of buchu is its bright fragrance, described as minty and fruity, and this is thanks to their abundance of essential oils. Often used to make herbal tea and as a medicinal plant, this family is deeply rooted in South African culture.

They’re native to South Africa and can be found in both fynbos and renosterveld locations, where they’re often seen growing on mountain slopes.

Like other fynbos plants, buchu is specially adapted to the conditions and is able to regenerate after wildfires, with some species keeping stores underground.

Rooibos Buchu (Agathosma crenulata)

Growing in the lower elevations of the South African mountains, rooibos buchu is an erect plant that produces pretty, white, star-shaped blooms. Nectar-loving insects are attracted to the flowers, particularly bees and butterflies, which ensure successful pollination.

The plant is sometimes called the oval-leaf buchu and has been used for its medicinal purposes, especially for relieving gastrointestinal issues. The Khoi and San people dry the leaves and turn them into a powder which is mixed with sheep fat and used to anoint people.

These plants can grow up to 8.2 feet (2.5 meters) and, once they have flowered, produce green fruits containing a single seed. These fruits fall to the ground and the seed is released. Sadly, it is reported that there has been a recent 20% decline in the number of wild rooibos buchu.

Round-Leaf Buchu (Agathosma betulina)

The round-leaf buchu is slightly smaller than the oval-leaf buchu, growing to around 6.6 feet (2 meters) in height. However, its leaves are just as fragrant, often used in traditional medicine as a cure for UTIs. However, the plant has been overharvested, and conservationists worry that this could lead to its demise.

This species is endemic to the Western Cape and produces pink or white flowers that are pollinated by butterflies and bees. As is the case with the rooibos buchu, this species also produces a single-seed pod that falls to the ground and splits open.

Interestingly, the round and oval-leaf buchus have a very similar chemical makeup aside from one compound; round-leaf buchu contains quercetin-dimethyl ether glucoside, but oval-leaf buchu does not.

7. Watsonia (Bugle Lily)

Watsonia, more often referred to as bugle lily, is a family that contains at least 52 known species in South Africa. With colorful tubular flowers growing on tall spikes, these plants are easily recognizable and can be seen growing in sunny spots in well-draining soil.

They’re found in both fynbos and renosterveld ecosystems and grow from bulbs in the ground. The benefit of this is that the plant is able to store energy and nutrients which aids in its growth, reproduction, and survival.

When there is a wildfire, these bulbs are stimulated and begin to regrow into a brand new plant.

Wild Watsonia (Watsonia borbonica)

Wild watsonia grows on rocky sandstone slopes and is found in the northwest and southwest portions of the Cape. These hardy plants can grow up to 6.6 feet (2 meters), and the most impressive growth is often seen after a wildfire event. In some locations, these plants will only flower in the two years following a fire.

One of their most beautiful characteristics are the sword-shaped leaves as well as the pink to purple blooms, although these can sometimes be white.

There are two further subspecies of wild watsonia, which can be differentiated by their uniquely directioned stamens and anther shapes. In any case, the flowers produce nectar early in the morning, attracting solitary bees for pollination.

Bugle Lily (Watsonia meriana)

Commonly known as the bul-bil bugle lily, this species is known for its large, showy flowers that bloom in orange or red. The leaves are long and lance-shaped, and the plant can grow up to 6.6 feet (2 meters) in height. This beautiful appearance makes it a popular choice in domestic gardens, as well as naturally occurring in the Cape Provinces.

Bugle lilies produce capsules that contain seeds but more commonly, the plant sprouts from a bulb under the ground, which allows it to regenerate after a fire. However, there are some subspecies that are unable to produce bulbs.

8. Geissorhiza (Cape Tulips)

Cape tulips, of which there are 80 types in South Africa, are some of the most distinctive and colorful flowers in the fynbos. They also have an amazing ability to survive challenging conditions before regrowing, thanks to being geophytes. A geophyte is a plant that is able to die back but retain an underground organ, often a bulb, tuber, or corm, and resprout when conditions are more favorable. So, when there are fires in fynbos, Cape tulips will be one of the first things to recover.

Rough Cape Tulip (Geissorhiza aspera)

The rough Cape tulip is a truly beautiful species that boasts blue star-shaped flowers and sword shaped leaves. This is a member of the Iridaceae family, more commonly known as the iris family and flowers between August and September.

If it weren’t for the fact that the rough cape tulip, which grows to around 14 inches (36 cm) in height, had adapted to growing well in urban areas, it may have struggled to survive. But now it is listed as being of least concern by SANBI.

This species grows at altitudes of up to 2,297 feet (700 meters) and is often found on sandy flats and slopes. While it was once endemic to the Western Cape, populations have now been noted in the north.

Pink Cape Tulip (Geissorhiza radians)

The pink Cape tulip is perhaps one of the most interesting looking species in the fynbos, with petals that are crimson at the base and blue/purple at the top. Because of this appearance, many say that they look like glasses of wine.

Pink Cape tulips are found in wet lowlands but sadly, habitat loss has meant that around 80% of its natural areas have been destroyed. What is left continues to be threatened by other factors like pesticide run off and invasive species.

These plants rely on pollination from insects within the horsefly family and they are attracted by the brightly colored petals.

9. Halleria (Tree Fuchsia)

Native to the eastern and southern parts of Africa as well as the island of Madagascar, Halleria is a genus from the Stiblaceae family. The genus contains just four species and is named after Albrecht von Haller who discovered it back in the early 1700s. Although we know these plants more commonly as fuchsias.

Tree Fuchsia (Halleria lucida)

The tree fuchsia is an evergreen species that has thick, glossy leaves, ideal for conserving water and can grow to between 39 and 66 feet (12 and 20 meters). Between April and October, the tree fuchsia blooms beautiful red tubular shaped flowers that are particularly attractive to birds, notably the sunbird which helps to pollinate it.

Tree fuchsia is found in various habitats, including coastal scrubs and evergreen forests where it thrives in well-drained soil.

Traditionally, the Zulu people would use the crushed up leaves to treat ear infections and skin disorders. What’s more, in folklore, this species is said to revoke evil.

Wild Fuchsia (Halleria elliptica)

Much smaller than the tree fuschia, the wild fuschia only grows to around 3.3-6.6 feet (1-2 meters) in height. However, this beautiful shrub, with its red to orange tubular flowers, is a popular addition to gardens in South Africa.

The flowers produce an abundance of nectar, which is highly attractive to the insects and birds that pollinate this plant. In the wild, it can be found in various environments such as scrub, forests, and rocky habitats.

Sometimes known as bush honeysuckle, this species is often used in horticulture to attract pollinators but also has a long history of traditional uses by the Zulu people.

10. Felicia (Blue Daisy)

Felicia, commonly known as blue daisy, is a genus of around 85 herbaceous plants. As the name suggests, the flowers have a daisy-like appearance and lots of nectar, which makes them highly attractive to pollinators.

While blue daisies do prefer well-drained soil, they are adaptive plants that will do well in various environments. They produce blue to purple flowers, but there are some species that display blooms in yellow, pink, or even white.

Blue Marguerite (Felicia amelloides)

Blue marguerite is an attractive plant whose bright blue 1.2 inches (3 cm) flower heads grow on top of single stalks. These stems are covered in small hairs which protect the plant from herbivorous insects. Typically, these plants grow to around 20 inches (51 cm) but, in rare cases, may reach double this height.

The blue marguerite blooms between September and March and is a well-loved garden plant owing to its very unique shade of blue. What’s more, this species grows in sandy soil and is known to be able to stabilize it.

While mainly pollinated by bees and other flying insects, blue marguerite is often found with a yellow flower spider in the center, which may also aid in pollination

An icon of South Africa, blue marguerite has even appeared on postage stamps.

Fine-Leaved Blue Daisy (Felicia filifolia)

The fine-leaved blue daisy is a unique-looking plant with thin-petalled flowers that come in mauve to white. But while the blooms may look delicate, this is actually quite a robust woody shrub that can grow up to 59 inches (150 cm).

One of the reasons that the fine-leaved blue daisy thrives so well in fynbos is its drought-tolerance. This also makes it popular in domestic gardens as it’s very easy to care for.

Pollinators love the colorful blooms, and their presence in turn attracts an array of bird species to the plant. There are four subspecies of Felicia filifolia which can be differentiated by their leaves. 

11. Syncarpha (Everlasting)

Syncarpha, more commonly known as everlasting, is a genus that contains 21 flowering plant species. This genus takes its common name from the fact that the papery flower bracts have the ability to last for months or even years.

These are very adaptable plants that can do well in various soil types and environments, and they’re well-loved for their vibrant colors, which are hugely attractive to pollinators.

Mountain Everlasting (Syncarpha eximia)

Mountain everlasting is a species that many people say looks like a bowl of strawberries when the blooms are budding. The thick leaves are arranged along an erect stem, which can grow up to 59 inches (150 cm) in height.

As well as having a unique appearance, the mountain everlasting is hailed for its medicinal properties and has long been used as a traditional remedy for things like liver disease and jaundice.

The mountain everlasting is typically pollinated by beetles and butterflies and is perfectly adapted to life in the fynbos with seeds that are stimulated by fire.

Silky Everlasting (Syncarpha canescens)

The silky everlasting may not be as showy as the mountain everlasting, with its small pink to purple flowers and bushy appearance, but it’s still as impressive because of its long blooming period that continues well into fall.

It often grows in rocky areas all over the fynbos and while not abundant, it is common. Frequently, you’ll find the silky everlasting among restios. However, it’s not a common garden plant as it’s pretty tricky to propagate.

12. Serruria (Blushing Bride)

There are 55 species of plant within the Serruria genus, and they come in an impressive array of colors from pink to white. These species are generally found along the coastline as well as in mountainous regions and are very attractive to insect and bird pollinators. 

The pretty flowers of the blushing bride, with their petal-like bracts, are delicate and unique, and many people say they look like a ready-made bridal bouquet.

Blushing Bride (Serruria florida)

Blooming in winter and spring, the blushing bride has delicate pink to white papery flowers that grow from the shrub. The needle-like leaves aid in reducing water loss, and each stem produces up to 8 flowers.

Sadly, the blushing bride is listed as critically endangered, although it does grow in the protected Hottentots Holland Nature Reserve. Parent plants die back after a fire, leaving the seeds behind, which only open when exposed to fire. However, the seedlings require at least two years before they mature, so frequent fires are partly responsible for the status of this species.

Because of its beautiful appearance, the blushing bride is often used as a cut flower for arrangements as well as being regularly grown in gardens.

Clustered Blushing Bride (Serruria fasciflora)

The clustered blushing bride is incredibly unique looking with narrow winding leaves and, as the name suggests, clusters of delicate pink flowers. In some regions these flowers bloom all year, but they are typically seen from around May.

Clustered blushing bride is found in sandy soils in the Western Cape, but it is listed as Near Threatened. The plant releases its seeds which drop to the ground. Chemicals produced by the seeds attract ants that then store them underground for germination at a later date, when conditions are optimal.

13. Aspalathus (Rooibos)

The term rooibos means red bush, and this plant is well-loved by humans who collect the leaves and make a traditional drink known as rooibos tea. Not only does this tea have a beautiful flavor, but it’s also believed to have several health benefits, including its antioxidant properties.

With various adaptations, rooibos is able to thrive in acidic soil with low nutrient availability and has deep roots that give it easy access to water. What’s more, many species within this genus have a symbiotic relationship with a particular type of bacteria that helps to absorb nitrogen from the soil. 

Rooibos (Aspalathus linearis)

Growing to around 6.6 feet (2 meters) in height, rooibos boasts yellow or purple flowers and is often found in sandy soils on mountain slopes. The needle-like leaves help to reduce water loss, but it is this very feature that makes the plant so attractive to humans.

The leaves are known to be high in vitamin C and are cultivated for rooibos tea, whose flavor can be altered by adding things like honey, sugar, lemon, or milk. This is something that has been recorded as far back as the 1700s.

Like many other plants in the fynbos, rooibos relies on fire to stimulate resprouting of its seeds.

Threats Facing the Fynbos

As many as 1736 fynbos plants are now at risk of extinction and are categorized as critically endangered, endangered or vulnerable. This equates to around 45% of all fynbos species, including the King protea which is the national flower of South Africa. 

One of the biggest threats comes from invasive species, but urbanization and climate change also play a role.

Urbanization & Habitat Loss

While humans do need to create urban areas in which to live, we have to keep in mind the devastating effect this has on the natural habitat of plants and animals. Sadly, far-reaching urban expansion has caused habitat loss for much longer than we might imagine, and things are only getting worse.

Not only is habitat being lost, but it’s also being fragmented by developments like those in the Cape Flats, which makes it more difficult for plants to reproduce as there aren’t as many of the same species in an area for pollen to be transferred. What’s more, this separation and loss of habitat means fewer viable places for birds and insects to reside, which has a knock on effect on pollination for the plants.

This can result in the elimination of certain species that simply do not have the resources to survive. With fynbos having many endemic species, this makes the area even more vulnerable as these plants are specifically adapted for their environment, and even small changes can cause problems. In particular, plants found in the coastal regions are especially at risk owing to their incredibly unique adaptations.

There are several examples of urbanization causing habitat loss in fynbos, including the expansion of the South African capital of Cape Town. Housing developments are now incredibly close to the edges of fynbos and even encroaching on it.

Not only this, but there is concern over the urbanization taking place around Table Mountain and the invasive species that are being brought with it. In Overberg, land is being used for vineyards and farming which has reduced the number of naturally occurring species. What’s more, when humans encroach on areas like this, there is often conflict between them and the wildlife, frequently ending in culling.

Invasive Species

Invasive species in fynbos are one of the leading conservation threats simply because they outcompete native plants for resources. However, once a species is introduced and begins reproducing, it can be hard to reverse as they often have a rapid rate of reproduction and are adaptable to various conditions.

In a lot of cases, invasive species will also impact pollinators by either preying on them, attracting them, or outcompeting them. This has a direct impact on the flora, which suffers as a result.

There are several species of plants and animals that are now found in fynbos that are, quite simply, wreaking havoc on the native plant life. One of the most concerning is the Australian acacia, which not only outcompetes fynbos plants but also alters the soil conditions, making it harder for native species to grow. Other species of acacia, such as the Acacia saligna have been introduced from Australia, shading native plants and even turning the sandy soil more dense when most fynbos plants prefer loose, well-draining soil.

Pine trees were first introduced to South Africa in the 1700s and benefited the economy because of forestry. However, their ability to spread seeds far and wide means they have quickly taken over. What’s more, these plants alter the soil and often outcompete native species for water. If that wasn’t enough, reports suggest that these pines were responsible for the out of control fires in Knysna back in 2007, fueling the blaze that destroyed more than 15,000 hectares.

And it’s not just non-native plants that are a problem, several species of invasive fauna also threaten the plant biodiversity in fynbos. For example, the European starling (one of the most notorious invasive species on the planet) made its way here in 1899 and has since outcompeted native birds that would help to pollinate fynbos plants.

Moreover, species of invasive ant, such as the Linepithema humile, more commonly known as the Argentine ant, have invaded the fynbos and had a significant impact on native insects. Again, this affects not only the pollination of native plants but also the seed dispersal, as many native ant species bury seeds below the ground ready for germination after a fire. 

Climate Change

Climate change has already had a devastating impact on the fynbos flora, and further shifts are expected to continue disrupting this ecosystem. The problem with fynbos plants is that they’re so well adapted to their unique ecosystem that they’re vulnerable and highly sensitive to even the smallest changes.

Of the more than 7,000 plants found in fynbos, as many as 68% are endemic, meaning that, if they were to go extinct in this region because of climate change, that would be the end of the species.

Sadly this is a very real threat, with reports of drought affecting Cape Town having the capacity to wipe out more than a third of fynbos plant species. What’s more, it’s projected that rainfall in the region could decrease by a further 30% before 2050. This could result in plants not receiving enough water as well as problems like soil erosion which in turn affects the number of available nutrients. 

In recent years, these droughts and warmer temperatures have been responsible for an increased number of fires. While many fynbos plants need fire to reproduce, you can have too much of a good thing. For example, some species, like the honeybush are harvested by humans, and the loss of such species could affect the local economy. 

Moreover, with warmer temperatures, there is concern that certain grass species may become dominant, meaning more competition for other plants, which could lead to their decline. 

Agriculture & Land Use

For thousands of years humans have used the land for farming and other purposes. While this may be essential to our survival, we have to be responsible and accept that our activity can pose a serious threat to plant life.

Alarmingly, reports suggest that the west coast renosterveld biome now only survives in as little as 3% of its previous range purely because of how agriculture is imposing on the region. In much of the renosterveld region, wheat farming is common, and the cultivation of this crop is severely disruptive to plants as well as resulting in habitat loss.

Moreover, the vineyards that are popping up all over Overberg are being placed within the fynbos biome and altering the very composition of the soil.

The use of pesticides in agriculture may be beneficial to the crops, but for local plants and wildlife, they’re toxic chemicals that could spell the end for certain species. Not only are these pesticides harmful to plant life but just as damaging to pollinator species like bees. Since many fynbos plants rely on insect pollination, a decline in these species has a direct impact on the reproductive abilities of the plants. 

Various agricultural practices can also have a serious effect on fynbos plants. For example, monoculture and an increased demand for water with farmers extracting groundwater not only impacts the quality of the soil and water availability but can also interfere with the nutrients that plants so desperately need.

While there are some farmers that are implementing action to decrease the threats to fynbos plants, such as having buffer zones and no-till farming, these will only have the greatest impact when done collectively.

Conservation Efforts to Protect the Fynbos

As I mentioned above, without the cooperation of all farmers, locals, conservationists, and researchers, the plants in fynbos will remain at risk. However, conservation of this biodiverse region is under way, which is great news for the many unique species that thrive here.

Protected Areas & Reserves

One of the most effective ways we can conserve fynbos is by creating protected areas where these plants are allowed to thrive in their natural conditions without interruption. If this happens, then the biodiversity of this region and the rare species that are found here will continue to live on.

There are currently numerous protected areas within and around fynbos, including many listed as UNESCO sites.

One fantastic example of a successful fynbos protected area is within the Table Mountain National Park, which is home to several endemic plants and backs the Fynbos Forever Program. This incentive is designed not only to protect the land but also the marine ecosystems that run alongside it.  

CAPE, working closely with the WWF is also working to protect the marine ecosystems of the fynbos as well as connecting areas where habitat fragmentation has been problematic for local vegetation.

Around the Western Cape, there are intentions to further increase the number of protected areas, joining existing areas such as the Cederberg Wilderness Area which is home to many mountainous fynbos species like the Leucadendron cederbergensis.

The Kirstenbosch National Botanical Garden, dubbed as one of the most beautiful botanical gardens on the planet, is home to three types of fynbos plants: proteas, ericas, and restios. Not only does this help to conserve species in a protected environment, but serves as an excellent way to increase public awareness and education.

Creating buffer zones between human land and fynbos areas can be useful in protecting these species from things like habitat fragmentation and loss. Of course, this requires cooperation with indigenous people, which is something else that conservationists are focusing on.

Fire Management Practices

Many fynbos plants rely on the heat and smoke from fire to stimulate their seeds into germination as well as for balancing the nutrients within the soil. Controlled burns are a great way to mimic natural fire cycles and this could have a wider positive effect on things like invasive species. With fewer naturally occurring fires, many of these fire-intolerant species could become dominant, although these blazes need to be carefully managed in order to have the desired effect and maintain ecosystem health.

Many of these prescribed burns take place in the protected areas I discussed above. Management teams need to consider the plant species that will be affected, how frequently fires need to happen, and how they will affect the overall health of the ecosystem. The control of these fires can be managed with things like firebreaks and controlling the fuel availability.

The good news is that the indigenous communities in South Africa have been using controlled fires as a way of managing the land for centuries. By working closely with these people, teams are able to develop safe and effective practices. There have been many examples of successful controlled burns that have helped to shape and manage the fynbos ecosystem, such as those implemented by the SANSParks which are timed with the seasons. 

Climate Change Strategies

Being totally honest, it’s unlikely that we will be able to reverse the effects of climate change quickly enough to have any positive effect on fynbos in the near future. Moreover, getting the planet to a place of greater sustainability will take time. However, there are several efforts in place that aim to improve the plant life in fynbos’ resilience to climate change.

For example, did you know that fynbos is thought to be the third largest carbon store on the planet, so protecting it is vital. In Cape Town, climate change strategies are being rethought with 35 new goals for the city.

What’s more, owing to the severe impacts of climate change within the fynbos, the Cape Floristic Region has become an important test area for conversationalists looking at these effects and finding new ways of managing them.

Invasive Species Management

Invasive species are one of the main threats to fynbos plants but with long-term commitment and cooperation from local communities, land owners, and researchers, this is a problem that could be handled successfully.

One of the most important things is that invasive species are detected as early as possible to reduce the risk of them taking over and outcompeting native plants. This will allow for their swift control and removal using strategies such as cutting, the introduction of natural enemies and predators, and herbicides. Of course, which methods are used will depend on the characteristics of the individual species.

Once these alien species are removed, this will allow native fynbos plants to recover, especially when individuals are reintroduced to the ecosystem. However, it’s important to note that this isn’t always an easy venture since many of these species are incredibly strong with deep set root systems and natural resistance.

In Cape Town, the deputy mayor is working on the removal of invasive species through the City’s Biodiversity Management’s Invasive Species Program around the area of the Battle Of Muizenberg. In other areas, such as the Cape Flats nature Reserve including the removal of post-burn invasive acacia species.

Of course, once alien species have been removed, teams still need to remain vigilant and ongoing monitoring is essential. What’s more, future strategies may need to be adapted according to the results of this monitoring. 

Public Awareness & Education

In a lot of cases, local people may not be aware of the human impacts on fynbos flora, which is why it’s so important to provide education. Helping people to understand the damage that the ecosystem would sustain because of the loss of these plants ensures that local communities and landowners are keen to get on board with conservation efforts.

The Fynbos For The Future program is designed to help local people reconnect with nature and renew their appreciation for these indigenous plants. What’s more, back in 2020, we saw the very first Fynbos Festival, which provided education in an entertaining setting.

And it doesn’t end there, many people are keen to visit the botanical gardens at Kirstenbosch, which provides an amazing opportunity to raise awareness to the challenges that fynbos flora faces as well as showing people what conservation efforts can be put in place. Bringing this education into schools  and community groups is also an effective way to draw awareness to the importance of preserving these areas.

For locals, pressing the value of indigenous plants can really hit home. Sadly, not many people think about this until the information is presented to them. But through workshops, online resources, and public events, awareness is growing. It’s then only a matter of time before people that live in and around the fynbos region become protective of these wonderful species.

The more that people realize why fynbos conservation is essential, the more likely they will be to advocate it and implement strategies of their own. Even outside of local communities, we can raise awareness through things like guided hikes and ecotourism that combine education with entertainment.
