Helleborus is a genus of evergreen perennials which blooms in late winter and early spring. The flowers have five petal-like sepals, varying from white to pink to rose-purple, frequently with interior spotting and contrasting yellow stamens. The sepals surround a ring of small, cup-like nectaries which are actually petals modified to hold nectar. The sepals do not fall as petals would, but remain on the plant, sometimes for many months. The dark green, palmate leaves are leathery and serrated, and may become scorched and tattered in extremely cold weather.
