American Hazelnut
Corylus americana
In the United States:
Native
· also called american hazelnut, american filbert
Honeybees visit American hazelnut for its abundant pollen from male catkins, providing an essential early-spring protein source when brood rearing ramps up but other forage is limited. Peak bloom occurs in April to May, coinciding with colony expansion needs. As a wind-pollinated shrub, it offers no nectar; it spreads via suckers, which may require control in managed landscapes, and attracts deer browsing.
