The Butternut tree is also known as the white walnut. It is a native to eastern Canada but rarely seen out here in the prairies. This is too bad because this is a simply a beautiful tree. It is a faster growing variety of the walnut family and often grows in a multi stemmed formation. The nut meat is delicious with a mild, sweet and buttery flavour. Expect to start to harvest nuts around 10 years of age and typically ripening in mid to late September. Butternut is one of the hardiest of the walnut species and do grow well in zones 2 and 3. They are slowly disappearing from their native range from butternut canker, so far its rarity here has helped it be free from it. Our seed source is from large healthy 50 year old tree just right outside of Edmonton, AB.
You’ll need a protected site from the wind for best success, as well rich deep soil is also preferrd. Butternut trees produce a substance named juglone, which occurs naturally in all parts of the tree, especially in the leaves, nut hulls, and roots.
