Shadbush serviceberry (Amelanchier canadensis) blooms in early spring with a profusion of small white flowers. This shrub or small tree is adaptable to a wide variety of habitats, from wet swampy areas to dry uplands. Shadbush, or shadblow, or Juneberry, grows from 10 to 20 feet tall and flowers best in full sun. It suckers quite freely. In fall the leaves turn showy red and orange.

Shadbush is a host plant for the caterpillars of red-spotted purple and viceroy butterflies. Butterflies and other insects nectar at the blooms. The hard-red fruits ripen in June, providing an early summer feast for many species of birds, including Scarlet Tanager, Rose-breasted Grosbeak, American Robin, Hermit Thrush, Red-bellied Woodpecker, Hairy Woodpecker, Tufted Titmouse, Cedar Waxwing, Blue Jay, and Gray Catbird. It is moderately deer resistant.
