Epimedium × rubrum, sometimes commonly called red barrenwort, is a cross between E. alpinum and E. grandiflorum. It is a rhizomatous, clump-forming perennial which typically grows 8-12″ tall and is primarily used as a ground cover or edger in shady or woodland areas. Racemes of short-spurred to spurless, red flowers (red sepals and pale yellow petals) appear above the foliage in spring. Compound, medium green leaves with pointed, spiny-toothed, heart-shaped leaflets (to 3″ long) on wiry stems form attractive foliage mounds. New leaves in spring emerge with a red tinge, mature to green and turn reddish in fall.
Small area ground cover or edger for shady areas. Mass in woodland gardens, wild gardens or naturalized areas. Also effective in partially shaded areas of rock gardens and border fronts. Grows well under trees. Edger for paths and walkways.
