Patterson Pride Plum
Black Walnut

The Patterson Pride Plum is known for its delicious flavor, with firm, sweet golden flesh and dark red skin that isn’t sour. The freestone plums can grow 4-5 cm in diameter and are well-suited for fresh eating, baking, and preserves. It can produce heavy yields that ripen in mid-September which is later than other plums.

C.F. Patterson developed the Patterson Pride Plum at the University of Saskatchewan. It is known for its semi-dwarf, weeping growth habit

Patterson Pride 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.

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.
