About

Drosera capensis (), the Cape sundew, is a perennial rosette-forming carnivorous herb in the flowering plant family Droseraceae. It is native to the Cape region of South Africa, where it grows in permanently wet, nutrient-poor habitats. Its elongated, roughly oblong leaves are held semi-erect and have a distinct petiole. It is quite a variable plant with several recognised growth forms, some of which develop a short stem. As in all sundews, the leaves are covered in stalked glands that secrete sticky mucilage. These attract, trap, and digest arthropod prey, obtaining nutrients that supplement intake from the substrate in which the plant grows. D. capensis has dramatically mobile leaves that curl around captured prey, preventing its escape and facilitating digestion.

First recorded in the late 17th century, D.

How to grow it

D. capensis is one of the most widely cultivated sundews. It is a relatively large, 'showy' species whose leaves exhibit dramatic movement in response to prey capture. It is easily propagated, grows rapidly, readily produces attractive flowers, and is considered very easy to grow.

Where it grows

The native range of D. capensis spans the full width of the south coast of the Western Cape province, extending north from Cape Town to Gifberg and eastward into the Eastern Cape as far as Port Elizabeth. It has been reported from Brandfontein near Bredasdorp; Elim; Houwhoek; Ceres; near the N7 road between Clanwilliam and Citrusdal; the Verlorenvlei River; Hermanus; Paarl; Table Mountain National Park; Diep River near Plumstead; Riversdale including the Korinte River; Franschhoek; Jonkershoek; Viljoenspas; the Tradouw Pass; Tulbagh Kloof; Theewaterskloof; and Bainskloof.
