Common Hackberry vs 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 native, cold-hardy shrub found in boreal forests, along slopes, and in open upland habitats. It fixes nitrogen in the soil, improving fertility and helping other plants grow, while its roots help stabilize slopes and disturbed ground. Fast to establish on poor soils, it is widely used in reclamation, restoration, and erosion control projects.

With its smooth grey bark and shiny green leaves, Green Alder often forms dense thickets that provide cover for birds and small mammals. Its seeds, buds, and catkins also supply food for wildlife. Green Alder is well suited for naturalization and ecological restoration.

Note: We use Green Alder for Alnus alnobetula subsp. crispa. This species is also known by many other common names, including Mountain Alder, Sitka Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.
