River Alder
Red Osier Dogwood

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.

Red Osier Dogwood is a small deciduous shrub that features deep red stems and twigs year-round, with creamy white flowers in the spring. This shrub will add a nice pop of color to your yard.

Red Osier Dogwood is an excellent soil stabilizer. It is fast growing and becomes drought tolerant once well established.
