Elaeagnus angustifolia, commonly known as Russian olive or oleaster, is a deciduous shrub or small tree that is native to Eurasia. It can grow up to 10-20 meters tall and has a spreading, bushy habit. The leaves are narrow and silvery-grey in color, and the bark is dark brown and fissured.
The plant is known for its hardiness and tolerance to a range of environmental conditions. It can grow in poor soils, drought conditions, and even saline soils. Russian olive is often planted as an ornamental tree, for erosion control, and for its edible fruit.
The fruit of Elaeagnus angustifolia is a small, oval-shaped drupe that ripens in the late summer or early fall. It is typically yellow or orange in color and has a sweet, tart flavor. The fruit is used in traditional medicine for its anti-inflammatory and antioxidant properties.
However, the plant is also considered invasive in some regions, including North America and Australia, where it can outcompete native vegetation and disrupt ecosystems. As a result, it is banned or restricted in some areas.
