Black Walnut

The Black Walnut is a deliciously flavoured walnut consisting of sweet-tasting meat with a rich aromatic tone. Popularly used in cooking, yet great raw or roasted too. These nuts are thick-shelled and take a bit of extra strength to crack open. Expect to harvest nuts around mid to late October.

Black Walnut trees start to produce walnuts around ten years of age. Highly regarded for its timber, yet because of its slow growth a rarity on the prairies. A beautiful tree that will be stunning in your yard. 

These are seedlings from productive Canadian Prairie (zone 3) sourced trees.

Growers Note: Planting location is important, so choose your planting site wisely. Black walnuts have the best success growing in sheltered yard sites or urban locations (micro-climate). In colder climates such as Zone 2, you can expect winter injury and difficulty producing nuts. It’s a slow-growing tree and also slower to break dormancy in the spring. 

Growers Note: Black Walnut trees produce a substance named juglone which occurs naturally in all parts of the tree, especially in the leaves, nut hulls, and roots. Choose your planting site wisely as it can inhibit the growth of blueberry, apple tree, crabapple, cotoneaster, azalea, rhododendron, lilac, white birch, larch, mugo pine, red pine, white pine, Norway spruce, silver maple, potato, tomato, pepper and eggplant.
