What it's good for, and what it isn't

A low evergreen perennial that opens large pure white flowers with yellow stamens from midwinter to early spring, often pushing up through snow. Give it part shade, shelter from cold winter wind and humus-rich, limy or neutral, well-drained soil. It grows slowly, takes years to settle and resents being moved, so it is harder to keep than the Lenten rose; every part is poisonous.

Watch out for

It is slow and tricky to establish, needing several years to settle, and should not be disturbed or divided. It fails in acid, waterlogged or summer-dry soil, in full sun and in hot positions; in the warm, dry lowland gardens of Central Europe it lasts only in a cool, part-shaded spot that can be watered. Leaf spot (black spot) and crown rot occur occasionally, and aphids and slugs can turn up on shoots and leaves. Wild plants are protected in several Alpine countries: buy only nursery-propagated plants.
