Common Hackberry
Green Alder

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.

Green Alder is a cold hardy, native shrub. It is often planted on infertile sites so it can fix nitrogen from the air and improve the soil quality.

Green Alder is known for its smooth grey bark and attractive shiny green leaves; it is commonly used in reclamation.
