Autumn Olive
"Autumn Olive, Elaeagnus, Oleaster, Japanese Silverberry"
Elaeagnus umbellate

Crowds out native plants species.
Somewhat drought tolerant.

A large deciduous shrub that can grow to 20 feet. Leaves are alternately arranged, elliptic to lancelet (shaped like a lance head), and smooth-edged. Mature leaves have a dense covering of lustrous silvery scales on the lower surface. Stems and buds also have silvery scales. Flowers are small, creamy white to yellow and tubular in shape; they grow in small clusters. The abundant fruits look like small pink berries, also with silvery scales. Autumn olive is easily confused with Russian olive, which has many similar characteristics. Unlike autumn olive, Russian olive often has stiff peg-like thorns, and has silvery scales coating both sides of its mature leaves.
