Fockea is a genus of succulent scrubs native to Africa south of the equator. They are members of the Asclepiadoideae (milkweeds), a subfamily of the dogbane family Apocynaceae. Of the six accepted species, only the two most widely distributed extend north of southern Africa, with F. multiflora reaching as far north as Tanzania and F. angustifolia reaching to southern Kenya. Fockea are known as water roots, a reference to the bulbous caudex characteristic of most species, which is also edible in at least some species.

Fockea is a genus of succulent scrubs native to Africa south of the equator. They are members of the Asclepiadoideae (milkweeds), a subfamily of the dogbane family Apocynaceae.

Fockea are known as water roots, a reference to the bulbous caudex characteristic of most species, which is also edible in at least some species.
==Taxonomy== The genus Fockea Endl. was established in 1838 by the Austrian botanist Stephan Ladislaus Endlicher through illustration and description of a specimen of Fockea capensis collected in Cape Colony circa 1786 by Franz Boos and Georg Scholl and cultivated at Schönbrunn Garden in Vienna. The genus was named after the German physician and naturalist Gustav Woldemar Focke, author of the commentary De respiratione vegetabilium (Of the respiration of vegetables). The "Old Lady of Schönbrunn" — the oldest potted succulent in cultivation — continued to be cultivated at least through 1988, over 200 years after it was first collected by Boos and Scholl. It was believed to be the last surviving member of its species until the South African botanist Rudolf Marloth collected another specimen of F. capensis near Prince Albert in 1906.
