Porthos Cherry
Arnold Hawthorn

Porthos Cherry is a cold-hardy dwarf sour cherry that features white spring flowers followed by large, dark red fruit in mid-to-late summer. Among sour cherries, Porthos is exceptionally sweet with well-balanced acidity. These cherries are ideal for fresh eating, freezing, baking, winemaking, and preserves.

Porthos Cherry was developed by the University of Saskatchewan Fruit Program as part of the Musketeer series and released in 2022. They recommended growing dwarf sour cherries as a shrub rather than a small tree. The shrub form tends to bear fruit earlier and is less susceptible to winterkill.

Sour cherries are self-fertile; however, planting with additional varieties for cross-pollination can increase yields.

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.
