Canada Plum
Arnold Hawthorn

Canada Plum is a cold-hardy wild plum native to North America with small red fruit. They ripen in mid to late summer, with bitter, astringent skin surrounding sweet, slightly acidic flesh that clings to the stone. While some enjoy eating the plums fresh, they are more commonly used for baking and preserves. It is considered a universal pollinizer for other plum varieties and is often used for grafting or as a rootstock.

White to pink flowers appear in spring, often before the leaves, providing an early source of nectar and pollen for native bees and other pollinators. Birds and other wildlife also feed on the fruit, adding to its ecological value. Canada Plum can grow as a small tree or large, multi-stemmed shrub. It is well suited to a variety of projects, including fruit orchards for cross-pollination, as well as pollinator plantings, naturalization, and restoration projects.

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.
