Beaked Hazelnut vs Green Alder

Corylus cornuta

Alnus crispa

Beaked Hazelnut
Green Alder

Beaked Hazelnut is a multi-stemmed, deciduous shrub native to North America.

It features smooth, grey bark and edible nuts. Beaked Hazelnut prefers a rich sandy-clay loam but will grow on poorer sites, and can be used as an understory shrub.

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.

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