Butternut is one of the few walnut varieties native to Canada. The nuts are sought after for their mild, sweet, and oily taste. Ensure this tree is planted in full sun and well-drained soil for best results.

Butternut is self-fertile but it has better yields when planted near other butternuts. It can survive in zone 2, but reliably produces nuts in zone 3.

A top CO2 absorbing species. Experts think this tree may help climate change more than others.

Pembina Plum is one of the best-tasting plums that can be planted on the prairies. It is semi-freestone with orange flesh that is soft, juicy, and sweet which contrasts with the thick, sour, dark red skin. The plums can grow up to 5 cm in diameter and are well-suited for fresh eating, baking, and preserves.

They typically ripen in mid to late August and should be picked as soon as they are ripe. If left too long, the fruit will fall off the tree.

Pembina Plum is a hybrid between Canada Plum and Japanese Plum. For fruit production, it needs to be planted with another variety for cross-pollination. Canada Plum and American Plum are considered universal pollinizers.
