autumn olive

Rhamnales > Elaeagnaceae > Elaeagnus umbellata Thunb.
Synonym(s): oleaster, silverberry

Autumn olive is a deciduous shrub from 3-20 ft. (0.9-6.1 m) in height. It is easily recognized by the silvery, dotted underside of the leaves. Leaves are alternate and 1 in. (2.5 cm) wide. Small, yellowish flowers are abundant and occur in clusters near the stems in May to June. Fruits are red, juicy, and edible. Fruits ripen from September to November. Autumn olive invades old fields, woodland edges, and other disturbed areas. It can form a dense shrub layer which displaces native species and closes open areas. Autumn olive is native to China and Japan and was introduced into North America in 1830. Since then, it has been widely planted for wildlife habitat, mine reclamation, and shelterbelts.
