Helleborus foetidus, known variously as stinking hellebore /ˈhɛlɪbɔːr/, dungwort, setterwort and bear's foot, is a species of flowering plant in the buttercup family Ranunculaceae, native to the mountainous regions of Central and Southern Europe and Asia Minor.

The drooping cup-shaped flowers appear in spring, and are yellowish-green, often with a purple edge to the five petal-like sepals on strongly upright stems.

The flowers, typically for the family, contain numerous stamens as well as up to ten nectaries which make them attractive to bees and other insects.

[2][3] H. foetidus is grown in gardens for its handsome evergreen foliage and large numbers of green, bell-shaped flowers borne in late winter.

It prefers woodland conditions with deep, fertile, moist, humus rich, well-drained soil, and dappled shade.
