Common Caragana
Grey Alder

Common Caragana is a fast growing shrub that's known for its exceptional hardiness and drought tolerance. Although it's most commonly planted in shelterbelts, Common Caragana is also an excellent hedge or feature shrub.

Note: in warmer areas, this species can be difficult to contain once planted. Use the right plant in the right place.

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.
