Anemone hepatica, the common hepatica, liverwort, kidneywort, or pennywort, is a species of flowering plant in the buttercup family Ranunculaceae, native to woodland in temperate regions of the Northern Hemisphere. This herbaceous perennial grows from a rhizome. Anemone hepatica grows 5–15 cm (2–6 in) high. Leaves and flowers emerge directly from the rhizome, not from a stem above ground. The flowers are blue, purple, pink, or white and appear in winter or spring. They have five to ten oval showy sepals and three green bracts.
