The buartnut is a cross of the butternut x heartnut found in Scotland, Ontario. This tree is unique because it is the only cross discovered so far that has the good qualities of the heartnut in shape and cracking with the hardiness of the butternut. These trees exhibit hybrid vigor, disease resistance, heavy bearing, superior hardiness and often very unusual nuts. By grafting we can continue these exceptional qualities. So far it seems to be resistant to the butternut canker. Winter protect grafted area of the tree in zone 5 for 2-3 years. Tree size can range from 10-15 m (40 ft) in height and spread.
'Mitchell' buartnut is the parent of these vigorous seedlings. A great deal of variability can be expected. Suited for climate zones 5a-8.
