Botanical Name

AMELANCHIER laevis 'Cumulus'

Plant Common Name

Allegheny Serviceberry, Cumulus Allegheny Serviceberry

General Description

This heavy blooming Allegheny serviceberry has a more narrow upright form than average. ‘Cumulus’ is an exceptional small tree admired for its beautiful spring flowers, edible summer berries and glorious fall color. This multi-stemmed deciduous small tree is North American in origin and naturally inhabits moist open woods and meadows.

Bronzy new leaves awaken in spring alongside its delicate white spring flowers. The simple oval leaves quickly turn medium green and burst into glorious shades of red, yellow and orange in fall. The showy flowers are white, five-petaled and held in pendent clusters. They are pollinated by bees and followed by small, round, berries that turn from rosy red to blue-black by summer. The fruit is edible to people and wildlife alike. In winter, its smooth gray bark adds stark winter interest.

Allegheny serviceberry grows best in full to partial sun and fertile, organic-rich soil. It is not too pH sensitive but does tend to favor slightly acid soil. It has a naturally attractive vase-shaped habit and should only be pruned lightly and selectively as needed. It tends to sucker and these should be removed from plants placed in more formal settings.

This is an ideal small tree for smaller landscapes and woodland gardens. It is also suitable for large foundation plantings. Its smooth bark and white flowers are best viewed against a background of evergreens.
