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. Another species (E. angustifolia) may also be native in southeasternmost Europe though may be an early human introduction there.
