Very variable species that usually grows as a shrub but can eventually grow into a small tree with a broad, ovoid crown. On emerging, the leaf has woolly hairs on the underside. These hairs disappear in the summer. The grey-green leaves vary in shape from a narrow oval to nearly round. The change of colour in autumn is not very spectacular: the leaf turns somewhat purplish red. The creamy white flowers open in erect racemes. They are of average size. The edible fruits are red at first, turning blue-black on ripening. Amelanchier has few soil requirements but grows best in calcareous soil.
