Title: Elaeagnus angustifolia (oleaster)
Description: Elaeagnus angustifolia: Native to southern Europe and western Asia, Elaeagnus angustifolia is commonly found growing along floodplains, riverbanks, stream courses, marshes, and irrigation ditches Seedlings are tolerant of shade and the plant thrives in a variety of soil and moisture conditions, including bare mineral substrates.E. angustifolia can withstand competition from other shrubs and trees and can spread vegetatively by sprouting from the root crown and sending up root suckers. The fruits float and are probably dispersed via water transport. Also, the seeds ingested with the fruit by birds and small mammals are dispersed in their droppings.
