Russian olive

Elaeagnus pungens is a species of flowering plant in the Elaeagnaceae family. It is native to Asia, including China and Japan, and has been introduced to other parts of the world, such as the southeastern United States, where it is commonly used in landscaping. It is also found in regions like Belgium, the Netherlands, France, and several U.S. states. Known by common names such as thorny olive, spiny oleaster, and silverthorn, it is sometimes referred to as an oleaster. Its widespread use in horticulture has led to its presence in many non-native habitats.
