Royal Purple Smokebush
Green Alder

Royal Purple Smokebush is an attractive and dramatic shrub. Mid-summer you'll notice feathery, purple-pink puffs of airy seed clusters that give the illusion of smoke. The contrast of these seed clusters against deep purple-red foliage will make Royal Purple Smokebush your new favorite shrub.

It is tolerant of clay soil, drought, and deer, making Royal Purple Smokebush a hardy addition to any yard. Try it in a hedge, shrub border, or as an accent shrub; regardless of how you use it, this shrub will be a head turner.

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.
