Arbutus–commonly called Strawberry Tree–is an evergreen shrub or tree that is cultivated for its decorative bark, flowers, and fruit. The bark is smooth, red-brown, and often peeling. The flowers are small urn-shaped and white or pink. The fruits are yellow or red and look like miniature strawberries.
Arbtus is a subtropical plant; it grows best where winters are mild. As a shrub Arbutus can be grown in a large shrub border or woodland garden. Grown as a tree, Arbutus is a good specimen plant with its colorful bark, flowers, and foliage.
Arbutus grows best in humus-rich, acidic soil, but it will tolerate alkaline soil. Arbutus should be protected from wind even when mature.
Arbutus is a genus of about 14 species of evergreen trees and shrubs native to the Meditteranean and from Western North America to Mexico and Guatemala.
