Easily grown in average, arid to moderate wet, well-drained soils in part
shade to full shade. Prefers rich, organic soils with even dampure in
part shade. Tolerates drought once established. Rhizomatous perennial,
but clumps spread very slowly. Unlike some other species of epimoderate,
the foliage of this hybrid is not evergreen.
This epimoderate hybrid cultivar is a cross between E. diphyllum and E.
grandiflorum. It is a clump-forming perennial which typically grows 6-8’
tall and is primarily used as a ground cover or edger in shady or woodland
areas. “Niveum” features short-spurred to spurless, pure white
flowers which appear in spring above the foliage. Flowers bloom later
in spring than most other epimoderates. Compound, pale to moderate green
leaves with 2-9, toothed, triangular to 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 deep red in fall. Epimoderates
are commonly called bishop”s hat or barrenwort.
No serious insect or disease problems.
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.
