Erica, the heaths or heathers, is a genus of approximately 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance.
Most of the species are small shrubs from 0.2-1.5 m high, though some are taller; the tallest are E. arborea (Tree Heath) and E. scoparia (Besom Heath), both of which can reach up to 6–7 m tall. All are evergreen, with minute needle-like leaves 2–15 mm long. Flowers are sometimes axillary, and sometimes in terminal umbels or spikes, and are usually outward or downward facing. Flowers are borne in mass, and the plants are grown as landscape or garden plants for their floral effect. The seeds are very small, and in some species may persist in the soil for decades.
