Common Name: Autumn Olive

Scientific Name: Elaeagnus umbellata

Habitat: Along streams, Ornamental

Provincial Designation: Prohibited Noxious

Prohibited Noxious weeds are plant species that are designated as "prohibited noxious" in the Alberta weed regulation. Prohibited noxious weeds must be destroyed, meaning all growing parts need to be killed or the plant's reproductive mechanisms need to be rendered non-viable.


Autumn olive is native to Asia and was brought to North America in 1830. It has been grown as an ornamental shrub, for food and cover for livestock, and as a windbreak.

Legislated Because

Autumn olive can grow into dense thickets and out-compete native vegetation. It also has nitrogen-fixing roots that can change the nutrient cycle in the soil making it difficult for native species to grow.


Autumn olive is a deciduous shrub that grows up to 4 m tall. The flowers are fragrant and have four white or light yellow sepals.

The characteristically silvery single leaves have smooth, wavy edges and are egg-shaped (2-7 cm x 1-2 cm).

Autumn olive fruits are 1 cm long, red and juicy with silver dots. The branches have single thorns and young twigs are silvery.
