prickly ash
Zanthoxylum americanum

Native
· also called common pricklyash, toothache tree, northern prickly ash
Honeybees visit prickly ash primarily for early-season pollen, with limited nectar available from the small, inconspicuous flowers. Peak bloom occurs in spring, providing a brief but valuable forage window before many other plants emerge. The thorny branches can form dense thickets, and the aromatic foliage may deter some pests, though pruning is needed to manage spread in landscapes.
