Common Hackberry

Black Cottonwood is the largest and tallest of the North American poplars. Named after its white, fluffy seeds with cottony hairs, this hardy tree produces sticky, fragrant buds and has a straight growth habit. Black Cottonwood needs ample moisture and nutrients to grow successfully to full height and are found in the Western provinces and the Yukon with BC being its heartland.

The Common Hackberry is a medium-sized deciduous tree that resembles the American Elm but is immune to Dutch Elm Disease. They are versatile and can adapt to a variety of growing conditions.

It produces purple-red, berry-like fruit with a large seed in the center. Both the sweet flesh, which tastes similar to dates, and the crunchy seed are edible. The fruit remains on the tree throughout the winter, offering a valuable food source for birds and other wildlife.

The Common Hackberry can also be a great addition to a pollinator garden. The tree itself is a host for the larvae of several butterfly species and the flowers provide a source of pollen and nectar.
