A North American native, is a large shrub or small tree that adds beauty to your landscape season after season. Fragrant white flowers appear in spring, along with the first leaf buds. Small edible purple-black fruits, favourites of birds, ripen in summer. The berries can be used for pies and jams. In the fall, the foliage is brilliant orange, yellow, or red. Silvery grey bark provides winter interest.

Botanical name: Amelanchier arborea
Plant type: large shrub or small tree
Zones: 4 to 9
Height: 15 to 25 feet
Sun: Full sun to part shade. In the wild it’s usually an understory tree, growing in the partial shade of larger trees.
Soil: Best in well-drained, slightly acidic loam; tolerates clay and sand.
Moisture: Prefers moist but tolerates dry or occasionally wet soil.
Pruning: Suckers freely from base and will form a dense shrub if not pruned. Can be pruned to form a small tree. Annual pruning is suggested.
Fertiliser: Don’t fertilise the first year after planting. After that, use organic fertiliser once a year.
Mulch: Add 2 to 4 inches of organic mulch to retain moisture and deter weeds. Leave a space between stems and mulch.

All in the family
There are many varieties of Amelanchier—some so similar that identification can be difficult. Among the most common are A. alnifolia (Saskatoon serviceberry), A. x grandiflora (apple serviceberry, a cross between A. arborea and A. laevis), A. laevis(Allegheny serviceberry) and A. stolonifera (running serviceberry).
