Opata Cherry Plum is considered to be one of the best tasting Cherry Plum varieties. It has a pleasant, sweet flavour and a hint of acidity. They ripen in mid to late August and are well suited to fresh eating, baking, and preserves.

The fruit is closer to a plum than a cherry but is smaller than most plums.The Opata Cherry Plum’s skin is red/green whereas the flesh is yellow-green. The flesh is freestone with a juicy, firm texture. Similar to other stone fruits, it does not store for very long.

The Opata Cherry Plum is a hybrid between a Western Sand Cherry and a Japanese (Chinese) Plum. For fruit production, it needs to be planted with another variety for cross-pollination. Canada Plum and American Plum are considered universal pollinizers.

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.
