Epimedium L.

Epimedium is a genus of about 25 species. Most representatives are native in the Mediterranean area (southern Europe, NW-Africa and SW-Asia) and temperate Asia, eastwards to China and Japan. Many of the species are cultivated as ornamentals. Stearn (1989) enumerates no less than 18 species and hybrids but only few are widespread in cultivation. Up to present two species have been recorded as escapes in Belgium.
