Green Alder vs Diablo NinebarkAlnus crispa Physocarpus opulifolius Diablo SOLD OUT SOLD OUT (we don't know if or when this product will be restocked) 
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. Diablo Ninebark is a small, low maintenance, multi-stemmed shrub, that is used to add texture or color to any yard. This plant grows dark purple leaves in the spring and grows slightly faster than Common Ninebark. It features flaky red to brown bark, clusters of white flowers, and long, maple-like leaves. Diablo Ninebark can make a dense and colorful hedge, or it can be an attractive ornamental by itself. GREEN ALDER QUICK FACTSDIABLO NINEBARK QUICK FACTS
