Japanese Silverberry (Elaeagnus umbellata) - Description
Elaeagnus umbellata, is known as Japanese silverberry, umbellate oleaster, autumn-olive, autumn elaeagnus, or spreading oleaster. The species is indigenous to eastern Asia and ranges from the Himalayas eastwards to Japan. Oleaster fruit is called "Senjed" in the Persian language. It is one of the key items in a traditional table setting of Nowruz, called "Haft-Seen", the traditional Iranian spring celebration. Because it fixes atmospheric nitrogen in its roots, it often grows vigorously and competitively in infertile soils.
