Wine Cup
Callirhoe involucrata (Malvaceae)

A hardy, drought tolerant, sprawling perennial native to Texas and the central United States. The numerous trailing stems spread vinelike over the ground originating from a carrot-like tuber. The magnificent dark purple-redor wine colred flowrs are numerous found at the end of slender stems. The flowers close each evening and remain permanently shut after polination. The stems and leaves of the entire plant die back in the heat of summer and should be trimmed to promote fall growth. Easy to grow from seed, or can be started from the carrot-like tuber. Prefers full sun in gravelly or sandy soils.
