Additional Information

Amelanchier laevis 'Cumulus' is a single-stemmed, strongly upright small tree, excellent as a small street tree and for very early, but short-lived, blooms. This tree is sometimes grafted, so rootstock suckers can be a problem. Fruits are edible and a prime source of food for birds. Subject to the troubles of Rosaceous plants in general, including fire-blight and mites, which can be controlled, usually quite easily.
