Shrub or small tree to 15 m tall Leaves: alternate, dark green, paler with a slight waxy whitish coating beneath (glaucescent), 3.2 - 8 cm long, elliptic to egg-shaped or oblong with a pointed tip and nearly heart-shaped or rounded base, more than twenty teeth per side, hairless or with a slightly hairy lower surface, with twelve to seventeen pairs of veins interconnecting near the margin. At flowering, the leaves are at least half-grown, bronze red, and nearly hairless. Flowers: borne on a slender, drooping, many-flowered inflorescence (raceme) 3 - 7 cm long, with nearly hairless individual flower stalks to 3 cm long. Each flower is white with a reflexed five-lobed corolla, narrow-oblong petals 1.5 - 2.2 cm long, and a hairless ovary tip. Fruit: berry-like (pome), clustered on 2.5 - 5 cm individual fruit stalks, purple or black, spherical, juicy, covered with a waxy whitish coating (glaucous), containing ten seeds. Twigs: slender, reddish brown, changing to dull grayish brown. Buds: green with a red tinge, 0.9 - 1.7 cm long, the inner scales lance-shaped with silky hairs along margin. Form: erect with irregular, spreading branches, not colony-forming.

Similar species: Amelanchier arbora, Amelanchier interior, and Amelanchier laevis are the three Amelanchier species in the Chicago Region that are taller than 3 m at maturity. Amelanchier arborea has hairy flower stalks that are less than 2.5 cm long, dryish fruit, and leaves that are folded, hairy and lack bronze red coloring at flowering. Amelanchier interior has eight to ten pairs of leaf veins and a densely hairy ovary.

Occurence in the Chicago region: native

Etymology: Amelanchier is the old French name of a species in this genus. Laevis means smooth-stemmed.
