Covered in sandy, nutrient-starved soils, scorched by fire, and pummelled by the prevailing gale-force southeaster in summer, the Cape Floral Kingdom has persisted as a land of extreme paradoxes for millenniums. Given the harsh conditions that assail life here, this world seems to have every reason not to be a botanical number cruncher’s wet dream: the untrained eye may hardly conceive that it gives refuge to nearly 20% of Africa’s flora on less than 0.5% of the continent’s surface. It seems implausible that some 9 000 plant species should thrive in these coastal extremities, 70% of which live nowhere else on Earth.
