American Elm
Ulmus americana
Honey bees eagerly collect high-protein pollen from American elm flowers in early spring, supporting brood rearing after winter; nectar is also gathered but in lesser amounts. Peak bloom occurs in March to April, providing an important early-season forage source. Trees are susceptible to Dutch elm disease, requiring vigilant management in urban or landscape settings.
