2005 PERENNIAL PLANT of the YEAR. The Lenten Rose is an easy spring blooming perennial for the shady woodland garden. Plants produce bushy clumps of thick, leathery evergreen leaves. Flower stalks appear in early spring, bearing showy cup-shaped blooms. This strain produces pristine white flowers with fully double petals. Site these where they will stay for many years, since the plants resent being disturbed. Trim the old leaves to the ground in late winter to give the flowers maximum impact. CAUTION: Harmful if eaten/Skin irritant.
