Grey Alder
Royal Purple Smokebush

River Alder is a large shrub or small tree with a multi-stemmed, spreading habit. It is an excellent tree to plant if you want to stabilize the soil near rivers and creeks.

Unlike the other alder varieties, River Alder is attractive enough to be included in riverside plantings by municipal and provincial park organizations.

Note: We use Grey Alder for Alnus incana. This species is also known by many other common names, including River Alder, Speckled Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

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.
