The Black Walnut is a slow growing, large, straight-stemmed and high value timber tree with an open crown. It produces a dense, very hard, edible nut. The root system usually includes a deep tap-root and several wide-spreading and deeply set lateral roots.
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.
Its 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.
Despite being highly valued for its edible nuts, high value timber, and its shade tree aesthetics, it is rare to see this tree on the prairies. Plant this tree once when it is young as it does not respond well to transplanting.
Although self-pollinating, planting two trees significantly improves nut production.
The seed for this tree was collected from a 45 year old tree in St. Albert that was originally planted on an acreage owned by John Beedle, a pioneer urban forester responsible for a number of pioneering tree, shrub and nursery innovations on the prairies as well as cold hardy fruit selections.
The large plug size will help this tree gets a good strong start.
