Noteworthy Characteristics
Epimedium × versicolor, sometimes commonly called bicolor barrenwort, is a cross between E. grandiflorum and E. pinnatum subsp. colchicum. 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.
Genus name is of unclear origin and meaning but the Greeks used epimedion for a very different plant.
Specific epithet means variously colored.
Epimediums are commonly called bishop's hat or barrenwort.
'Discoler' has short-spurred yellowish flowers with pale pink sepals, yellow petals and reddish spurs that appear in racemes 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 coppery-red, mature to green and turn reddish in fall. Synonymous with Epimedium × versicolor 'Versicolor'.
Problems
No serious insect or disease problems. Watch for aphids. Mosaic virus.
Uses
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.
