About This Species

Russian olive (Silver berry, Oleaster) is a short invasive tree that can survive in dry conditions,cold temperatures and poor soils. It was introduced from its native range in Russia and Aisa. It drinks more water than most plants in dry soil settings, therefore it can outgrow and compete with native species. Seeds are spread from bird droppings and wildlife eating the berries, as well as through flowing water and by beaver activity. 

How to Identify

Russian olive is a small ornamental tree with black bark that can grow 3–8 m tall. 

Flowers are small, yellow and fragrant flowers, and its edible silver fruit resembles olives. 

Leaves are long, narrow and silver.
