Bracted Honeysuckle
Green Alder

Bracted Honeysuckle is a shade loving shrub that is distinguishable from other honeysuckles by its square stem and pointed leaves. Native to most of North America, this honeysuckle is found along swamps, rivers, riparian zones and moist wooded areas.

If you have a erosion control project in mind, consider Bracted Honeysuckle.

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.
