Green Alder vs Mock OrangeAlnus crispa Philadelphus coronarius 
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.
Mock Orange's white flowers look and smell like those of the orange, with a hint of jasmine in the scent. It is an excellent ornamental shrub. People love the contrast between its flowers and dark green leaves. GREEN ALDER QUICK FACTSMOCK ORANGE QUICK FACTS
