Elaeagnus umbellata

It is a hardy, aggressive invasive species able to readily colonize barren land, becoming a troublesome plant in the central and northeastern United States and Europe.

[5] Elaeagnus umbellata grows as a deciduous shrub or small tree, typically up to 3.5 metres (11 ft) tall, with a dense crown.

[5] In the early 19th century, E. umbellata was purposely introduced to the U.S. and the United Kingdom for shelter belts, erosion control, wasteland reclamation, wildlife habitat, and for gardens as an ornamental.

[5] By the late 20th century, the shrub became a noxious weed and invasive species in many U.S. states from the east coast to the central prairies, and spread widely across Europe.

[5] Due to its substantial seed production and avid germination potential, E. umbellata rapidly invades new areas where it can resprout readily after burning or cutting.
