oleaster , common name for members of the Elaeagnaceae, a family principally of shrubs with leathery leaves and a dense covering of glistening hairs. Most members of the family are steppe and rock plants of the Northern Hemisphere; a few species are indigenous to the United States. Several are cultivated as hardy ornamental shrubs, especially the buffalo berry ( Shepherdia argentea ), whose edible fruits were gathered by Native Americans and by the Alaskan Eskimos; the common oleasters ( Elaeagnus angustifolia and related species); and the sea buckthorn ( Hippophaë rhamnoides ), a... oleaster.

oleastertree also called Russian olive , or trebizond date (species Elaeagnus angustifolia)
Main
small deciduous tree of Eurasia, about 4.5 to 6 m (15 to 20 feet) high. It has smooth, dark brown branches that often bear spines and narrow, light green leaves that are silvery on the undersides from a covering of minute scales. The flowers are small, greenish, fragrant, and silvery-scaled on the outside, as are the edible, olive-shaped, yellowish fruits, which are sweet but mealy. The oleaster is hardy, wind resistant, tolerant of poor, dry sites, and thus useful in windbreak hedges, but it is also widely used in ornamental hedges.

Species
See text
Elaeagnus (Silverberry or Oleaster) is a genus of about 50–70 species of flowering plants in the Elaeagnaceae. The vast majority of the species are native to temperate and subtropical regions of Asia, with one species (E. triflora) extending south into northeastern Australia, and another species (E. commutata) restricted to North America. A third species (E. angustifolia) may also be native in southeasternmost Europe, though it may be an early human introduction there.
They are deciduous or evergreen shrubs or small trees with alternate leaves. The leaves and shoots are usually covered with tiny silvery to brownish scales, giving the plants a whitish to grey-brown colour from a distance. The flowers are small, with a four-lobed calyx and no petals; they are often fragrant. The fruit is a fleshy drupe containing a single seed; it is edible in many species, though generally lacking a good flavour. Several species are cultivated for their fruit, including E. angustifolia, E. umbellata and E. multiflora (gumi). Although they are cultivated more in China than elsewhere, they are growing in popularity in the rest of the world.
E. umbellata is reputed to have a high amount of the carotenoid antioxidant, lycopene[citation needed] and has been shown to display antioxidant properties effective against cancer mechanisms in vitro[1]. E. multiflora is among the nutraceutical plants that Chinese use both for food and medicine[citation needed]. Both berries are small, but tasty and abundant.
Elaeagnus species are used as food plants by the larvae of some Lepidoptera species including Coleophora elaeagnisella and The Gothic.
