Green Alder
Wild Privet

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.

Wild Privet is a fast growing ornamental shrub that is well suited for forming hedges and privacy screens. It will retain its leaves in warmer climates but drops them in colder areas. They have small white flowers, though the smell is often considered unpleasant. While the berries are inedible, they are a good food source for many bird species.

It is recommended to prune Wild Privet immediately after flowering, as it can readily self seed. It is deer and rabbit tolerant. It can grow in dry areas, on slopes, and withstand the wind making it well suited for many growing conditions.
