Green Alder vs Silver Leaf Willow

Alnus crispa

Salix alba sericea

Green Alder
Silver Leaf Willow

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.

Green Alder is known for its smooth grey bark and attractive shiny green leaves; it is commonly used in reclamation.

Native to North America, Silver Leaf Willow has orangish bark and long, silvery grey leaves. Bees and other insects are attracted to its flowers.

Popular as an ornamental tree for parks, it is also used as a shelterbelt species. It may not be as cold hardy as some of the other willow varieties, however.
