Amelanchier laevis ‘Cumulus’ – Cumulus Allegheny Serviceberry

Botanical Name: Amelanchier laevis ‘Cumulus’

Alternate Name: Cumulus Allegheny Serviceberry

Allegheny serviceberry is an introduction from Princeton Nurseries in New Jersey.  It can be considered a small upright tree or a large shrub.

The 5-petaled, slightly fragrant, white flowers droop in clusters in early spring (April) before the leaves. Flowers give way to small, round, edible berries which ripen to dark purplish-black in June (hence the sometimes common name of Juneberry) and resemble blueberries in size, color and taste. The leaves are finely-toothed and emerge in spring with a bronzish-purple tinge. The leaves of the Cumulus serviceberry mature to lustrous dark green in summer and turn red-orange in fall.

This is a good selection for native plant areas. Shrub forms can be grown as tall informal hedges or screens and are attractive to wildlife. Its tolerance to some urban pollution makes this a good choice to use in smaller landscapes and under power lines.

Cumulus Allegheny Serviceberry is also resistant to verticillium wilt.
