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.

Falsebox is a hardy, native evergreen shrub found in forests, rocky slopes, and open woodland sites. Though small and easily overlooked among the leaves, the maroon flowers still supply nectar and pollen for pollinators such as native bees and flies. Blooming in spring, they provide an important early-season food source. Its year-round greenery adds visual interest through the winter.

Falsebox is a low-growing shrub that tolerates a wide range of conditions, including drought once established. It thrives particularly well beneath the shade of mature trees, where few other plants succeed. With its resilience and ecological value, Falsebox is well-suited for naturalization, restoration projects, and diverse landscape plantings.
