The Black Walnut is a slow growing, large, straight-stemmed tree with an open crown. It produces dense, very hard, edible nuts.

Black Walnut has a deeply-furrowed, black bark. Its leaves are about 1 foot long, composed of 15 - 23 slightly stalked leaflets on a moderately stout stock which provide good dappled shade.

Despite being highly valued for its edible nuts and its shade tree aesthetics, it is rare to see this tree on the prairies.

Note: Black Walnut's roots produce a substance named juglone that is toxic to some other plants. Consider this when choosing where you plant a black walnut, as you will not be able to grow tomato, potato, cabbage, eggplant, blueberry, azalea, rhododendron, lilac, red pine and apple in the surrounding area.

Note: Plant this tree once. It will not respond well to transplanting.

Note: Although self-pollinating, planting two trees significantly improves nut production.

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.
