Amelanchier × grandiflora is a hybrid cross between two species of North American serviceberry, namely, A. arborea (downy serviceberry) and A. laevis (Allegheny serviceberry). This is a small, deciduous, understory tree which typically matures to 15-20’ tall. Flowers bloom in April followed by edible fruits (3/8" diameter) in June (hence the sometimes used common name of Juneberry for amelanchiers). Berries resemble blueberries in taste and may be used in jams, jellies and pies. Finely-toothed, oval-lanceolate leaves (to 3" long) emerge with bronze tints in spring, mature to dark green from late spring throughout summer before finally turning brilliant red to orange-red in fall.
'Autumn Brilliance' has brilliant orange-red fall color (hence the cultivar name).
Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Tolerant of a somewhat wide range of soils, but prefers moist, well-drained loams. Root suckers are common, and if not removed, will result in a shrubby growth habit for the plant.
