Drosera acaulis

A tiny rosette sundew from the high mountains of the south-western Cape in South Africa, with about eight narrow spoon-shaped leaves under 1 cm long and single red or purple flowers about 6 mm across on very short stalks. It is found only in the Cederberg, Winterhoek, Skurweberg and Hex River mountains, in moist places above 1500 m. Grow it like a cool, bright, winter-growing Cape sundew with constant moisture, and expect it to be demanding.
