Autumn Olive
Elaeagnus umbellata
In the United States:
Invasive
· also called autumn olive, japanese silverberry
Listed as invasive. Check local regulations — several jurisdictions restrict planting.
Honey bees forage on autumn olive primarily for its abundant nectar, providing one of the earliest significant honey flows of the season from April to June with peak bloom in mid-May. Pollen rewards are minimal, with bees rarely collecting it. As a highly invasive shrub in eastern North America, beekeepers should avoid planting it and focus on removing existing stands to prevent ecological harm.
