Elaeagnus umbellata, commonly known as Autumn Olive, is a deciduous shrub species belonging to the Elaeagnaceae family. This plant species can grow up to 6 meters in height and 4 meters in width. The bark of the shrub is reddish-brown in color and is marked with numerous small dots, called lenticels. The leaves are alternate, simple, and elliptical in shape, with a silvery-grey color on the underside and dark green on the upper side.
The species is native to Asia, but has been introduced to other regions of the world, including North America, where it has naturalized and is considered invasive. Autumn Olive is known for its ecological benefits, such as its ability to fix nitrogen in the soil, prevent soil erosion, and provide habitat for wildlife species.
Overall, Elaeagnus umbellata is a highly versatile and ecologically important shrub species that has both ecological and economic value. However, it should be noted that its invasive nature can cause ecological problems in certain regions where it has been introduced.
