Cotinus coggygria Royal Purple

NOT AVAILABLE THIS SEASON

Green Alder
Royal Purple Smokebush

Green Alder is a cold hardy, native shrub. It is often planted on infertile sites so it can fix nitrogen from the air and improve the soil quality.

Green Alder is known for its smooth grey bark and attractive shiny green leaves; it is commonly used in reclamation.

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.
