Grey Alder

Ninebark is a small, multi-stemmed shrub, that is used to add texture or colour to any yard.

It features flaky, cinnamon-brown bark, attractive white flowers, and long, maple-like leaves.

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.
