Arnold Hawthorn

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.

Arnold Hawthorn is a low-branched tree favored by wildlife and landscapers. This tree's beautiful white flowers and bright red berries make it an attractive ornamental in anyone's yard. Arnold Hawthorn is also used in windbreaks and riparian planting.

Despite its thorns, Arnold Hawthorn is a popular choice of food and shelter for deer and birds. Humans can also eat these berries fresh or preserved, but Arnold Hawthorn will not have high yields until it matures at 5-8 years.
