Aldara Hazelnut
Black Walnut

Aldara Hazelnut is a northern hybrid selection noted for its superior nut quality, disease resistance, and cold hardiness.

It is great for attracting wildlife with the added bonus of edible nuts that can be eaten fresh or used in baking. Pair with another Aldara or Andrew Hazelnut for cross pollination to occur.

Aldara and Andrew Hazelnut are currently the hardiest and most reliable nut varieties available for the Canadian prairies.

Note: You want more than one hazelnut to improve yields.

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.
