Green Alder

Korean Boxwood is a vibrant evergreen shrub. A top choice for colder climates, this shrub will look stunning lining a driveway or as a foundation plant.

Easy to root in and maintain, Korean Boxwood's thick foliage is deer resistant and turns an attractive yellow-brown to purplish in winter. Consider applying mulch around the base to keep the roots moist and cool.

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.
