s are white, with five quite separate petals and five sepals. In ''A. alnifolia'', they are about across, with 20 stamens and five styles, appearing on short racemes of 3–20, somewhat crowded together, blooming from April to July. The fruit is a small purple pome in diameter, ripening in early summer in the coastal areas and late summer further inland. Resembling blueberries, it has a waxy bloom. Serviceberries are relatively difficult to identify.

Cultivation

Seedlings are planted with between rows and between plants. An individual bush may bear fruit 30 or more years. Saskatoons are adaptable to most soil types with exception of poorly drained or heavy clay soils lacking organic matter. Shallow soils should be avoided, especially if the water table is high or erratic. Winter hardiness is exceptional, but frost can damage blooms as late as May. Large amounts of sunshine are needed for fruit ripening.
