This epimedium hybrid (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. ‘Sulphureum’ features short-spurred yellow flowers (pale yellow sepals, bright yellow petals and deep yellow spurs) which 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 of this cultivar usually emerge reddish tinged in spring, mature to green and turn reddish in fall. Epimediums are commonly called bishop’s hat or barrenwort.
