Green Alder

Black Cherry is common in eastern North America but a rare find elsewhere. This tree is shade tolerant and is often found in old fields, forest openings, and along fencerows.

The fruit is edible and is commonly used to flavor rum and brandy. It is also edible and often eaten fresh or used in wine or jelly. Black Cherry trees typically begin producing fruit when they are 10 years of age.

Black Cherry wood is a rich reddish-brown color and is strong, making it valued in cabinetry and woodworking. It is often used in reclamation as well.

The leaves can poison livestock as they contain cyanide derivatives and precursors. However, many have noted that deer still seem to browse their trees with impunity and birds and other animals eat the fruit when available.

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.
