Autumn Olive (Elaeagnus umbellata) is a woody shrub that was intentionally introduced to the US in the early 19th century for use in shelter belts, erosion control, wasteland reclamation, wildlife habitat, and as an ornamental species.

Growing up to 20’ in height, autumn olive stems and branches bear small thorns. Small white flowers are intensely fragrant, developing into red berries in the fall.

Plants are spread through seed dispersal. Birds and other animals consume the abundant fruit, which is thought to be of low nutritional value, especially compared to the fruit of native plants that outcompeted by autumn olive.
