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.

American Plum is a cold-hardy wild plum native to North America that grows as a small tree or large multi-stemmed shrub. Small, firm, red plums ripen from mid to late summer; the skin is tough and tart, whereas the flesh is sweet and juicy. While some enjoy eating them 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.

In spring, American Plum produces abundant white to pink flowers that attract a variety of pollinators, providing an important early-season source of nectar and pollen. It also serves as a host plant for numerous moth and butterfly species. In its native range, it is recognized as an important keystone plant, as it has a disproportionately large impact on local ecosystems.

American Plum tolerates a wide range of soil conditions, from acidic to alkaline, and heavy clay. It is well suited to a variety of projects, including fruit orchards for cross-pollination, as well as pollinator plantings, naturalization, and restoration projects.
