Comments: This barrenwort hybrid 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 which appear in racemes above the foliage in spring. Compound, medium green leaves with pointed, spiny-toothed, heart-shaped leaflets 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.
