It is a deciduous shrub or small tree growing to 0.5–8 m tall with one to many stems and a narrow, fastigiate crown. The leaves are alternate, simple, ovate to ovate-oblong, 1–5.5 cm long and 1.8–2.8 cm broad with a rounded to sub-acute apex; they are downy below, and have a serrated margin and an 8–15 mm petiole. The flowers are produced in early spring in loose racemes 4–6 cm long at the ends of the branches; each raceme has four to ten flowers. The flower has five white petals 7.6–11 mm long and 2–4 mm broad, and 20 stamens. The fruit is a pome, 7–10 mm diameter, dark purple when ripe; it is edible and sweet. Fruits become ripe in June and July in its native range.
Amelanchier canadensis, commonly called shadblow serviceberry, is a deciduous, early-flowering, large shrub or small tree which typically grows 15-30' tall. Features showy, 5-petaled, slightly fragrant, white flowers in drooping clusters which appear before the leaves emerge in early spring. Finely toothed, elliptic, medium to dark green leaves (1-3" long) change to orange-red in autumn. Flowers give way to small, round, green berries which turn red and finally mature to a dark purplish-black in early summer. Edible berries resemble blueberries in size and color and are used in jams, jellies and pies.
Genus name comes from a French provincial name for Amelanchier ovalis a European plant in this genus.
Specific epithet means from Canada which is part of the native range of this plant.
