Black Walnut Trees are a relatively rare tree for Southern Alberta but they have long been successfully grown in Medicine Hat. They make excellent shade trees and offer a splendid dappled shade with their loose open canopy. As a delicious autumn treat they produce large bounties of rich tasting nuts. They are low maintenance and exceptionally pest and disease resilient. They produce a brilliant fall show of bright yellow leaves. All and all we can not say enough good things about the Black Walnut tree as a consideration for anyones yard with appropriate space.
