Barrenwort Epimedium grandiflorum 'Alba' |
This epimedium (sometimes commonly called large-flowered or longspur epimedium) is one of the larger epimediums. It is a dense, rhizomatous, clump-forming perennial which typically grows 10-12" tall and is primarily used in shady or woodland areas. 'Alba' produces racemes of long-spurred, white flowers in spring well above the foliage. Compound, medium green leaves with spiny-toothed, oval leaflets (to 3" long) on wiry stems form attractive foliage mounds. New leaves in spring emerge beige with a red tinge, mature to green and turn red in fall. This is a unique small area ground cover or edger for shady areas. It is also effective in partially shaded areas of rock gardens. Epimediums grow well under trees, as path edgers and even walkways that are shaded.
