Best grown in organically rich, humusy, well-drained soils in part shade to full shade. Locate plants in areas protected from cold winter winds. Clumps establish fairly quickly. New plants can be obtained from division of the clumps (best in spring) and from seedlings which grow up around the plants as a result of self seeding. A slightly larger and much easier plant to grow than the similar, but earlier blooming, Helleborus niger.
Lenten rose is a clump-forming, late winter-blooming perennial which typically grows 1-1.5' tall. Features large, cup-shaped, rose-like, usually nodding flowers (3-4" diameter) with center crowns of conspicuously contrasting yellow stamens. Flowers usually appear in clusters of 1-4 on thick stems rising above the foliage. Flower color is extremely variable, ranging from white to pink to light rose-purple, frequently with interior spotting. Palmate, serrate, leathery, 8-16" wide, glossy, basal, dark green leaves (7-9 leaflets) are evergreen in warm climates but deciduous in extremely cold winters. In the St. Louis area, plants will remain evergreen in moderate winters, but may become scorched and tattered in extremely cold weather, particularly if not insulated by snow cover. Blooms in late winter (sometimes when snow is still present) and continues into spring, with a long, 8-10 week bloom period. Leaves, stems and roots are poisonous.
No serious insect or disease problems. Leaf spot and crown rot are occasional problems. A rugged and easy-to-grow plant.
Clumps of Lenten rose blooming in February are true harbingers of spring. Locate plants near a kitchen window, patio or walkway so that the early bloom may be enjoyed to the fullest. Group in shady locations under trees or large shrubs, woodland gardens or border fronts. May also be incorporated into a naturalized area where clumps will slowly spread through self-seeding. May also be massed to form an attractive ground cover.
