tree of heaven

Ailanthus altissima
In the United States: Invasive · also called stinking sumac, Chinese sumac
Listed as invasive. Check local regulations — several jurisdictions restrict planting.

Honeybees actively forage on Tree of Heaven for its plentiful nectar and moderate pollen supplies during the late spring to early summer bloom. The inconspicuous flowers, arranged in large panicles, offer a brief but intense foraging opportunity, typically lasting a few weeks per tree. This fast-growing species thrives in disturbed, urban, or poor soil habitats and requires management to prevent it from forming thickets due to prolific suckering.
