Fynbos ("fine bush" in Afrikaans) is dominated by proteas, ericas, and restios and thrives in a small strip of South Africa's southwestern coast, yet it contains an extraordinary concentration of plant species found nowhere else on Earth. Kirstenbosch National Botanical Garden, at the foot of Table Mountain, alone cultivates several thousand of the region's plant species and is considered one of the great botanical gardens of the world.

Frequently Asked Questions
How did such a small area come to have so many plant species?
The region's mix of nutrient-poor soils, a Mediterranean-style climate, and periodic natural fires created ideal conditions for plants to evolve into highly specialised niches over millions of years, driving one of the highest rates of plant diversification found anywhere.
Why is the Cape Floristic Region classed as its own "floral kingdom" rather than just part of Africa's flora?
Botanists classify the world's flora into a handful of kingdoms based on shared evolutionary origins and distinctiveness, and the Cape region's plants are different enough from the rest of southern Africa's vegetation that it earns recognition as a floral kingdom in its own right, despite covering a comparatively tiny area.
How does this affect conservation efforts today?
Because so many fynbos species exist only in this narrow coastal strip, urban expansion and land-use change around Cape Town pose an outsized extinction risk, making protected areas like Table Mountain National Park and botanical gardens like Kirstenbosch critical to preserving species found nowhere else.
