Black locust**
Robinia pseudoacacia
In the United States:
Native
Honeybees visit black locust trees extensively for the abundant nectar and pollen produced during their fragrant white blooms, contributing to a valuable light-colored honey flow. Peak bloom occurs in late spring over approximately 10 days, making it a short but intense foraging period that benefits from nearby hives. The tree's vigorous suckering and thorny branches require management to control spread and avoid injury in plantings.
