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.
Black Elderberry is a deciduous shrub native to eastern North America. You can plant this shrub in moist areas and it will help stabilize your soil. You can also use it on rural properties anywhere you'd use a lilac. GREEN ALDER QUICK FACTSBLACK ELDERBERRY QUICK FACTS
