Drosera californica

Drosera × californica is a named hybrid within the thread-leaved sundew group of the southeastern United States (D. filiformis and its Gulf Coast relative D. tracyi); the widely grown 'California Sunset' belongs here. It forms erect, thread-like leaves from a small rhizome and makes a tight winter bud in cool short days. Grow it like its parents: full sun, pure water, wet peaty sand, and a cool winter.
