River Alder
Green Alder

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: Unfortunately this difficult to grow species is not currently scheduled to grow at TreeTime.ca. Perhaps try purchasing seed from SeedTime.ca and growing your own? Or sign up for a restock notification above.

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.
