Callirhoe involucrata

Callirhoe involucrata is a species of flowering plant in the mallow family known by the common names purple poppy-mallow, winecup and buffalo rose. It is native to the Great Plains of the United States and adjacent areas in northern Mexico.

The leaves and stems die back in winter, showing at most a small rosette of green leaves immediately above the root crown.

Cultivation
The purple poppy-mallow is one of the most faithful plants in production of vivid blankets of colors according to writer Claude A. Barr. Each plant can cover a great deal of ground with masses of its interestingly cut leaves and many wine-crimson cup shaped flowers. In suitably sandy or well draining soils each plant will produce a large parsnip like root. A good water thrifty ground cover.
