The habitat of this plant is woods and copses. Mezereon has the shrub habit. The branches are few and erect. The leaves are deciduous, inversely egg-shaped or spoon-shaped, lance-shaped, narrow below, acute, membranous, stalked, and appear after the flowers. The flowers are usually in threes, stalkless (or nearly so), lateral in the axils of the previous year's leaves, purple, pink, rarely white. The tube is hairy, as long as the lobes, which are egg-shaped, acute. The fruit - a berry - is bright red, egg-shaped. The plant is 1-3 ft. in height, flowering in March, and is a deciduous shrub.
