Facts About

Eastern shadbush is a 6-20 foot (2-6.5m) tall tree that produces white flowers in March and sweet, edible berries in June (around the same time as the annual shad run in New England). The smooth, light grayish-brown bark has vertical dark stripes. With a graceful, arching growth form that resembles alder, as well as reddish fall color to the leaves and edible fruits, this species makes a pleasant backdrop planting for the garden.
