Green Alder vs ButternutAlnus crispa Juglans cinerea SOLD OUT SOLD OUT 
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.
Butternut is one of the few walnut varieties native to Canada. The nuts are sought after for their mild, sweet, and oily taste. Ensure this tree is planted in full sun and well-drained soil for best results. GREEN ALDER QUICK FACTSBUTTERNUT QUICK FACTS
