Heartnut

The heartnut is a seed sport of the Japanese walnut. Rather than the normal egg-shaped Japanese walnut shell, the heartnut is a flattened heart-shpaed nut that readily splits in two halves. When rapped on the edge, it opens like a locket, easily releasing the kernel. All of our selections have rated highly for cracking quality, nut quality and productiveness. The heart shape with the good cracking quality may not come true in the seedlings as it does in the grafted trees. Heartnuts are generally hardier and walnut blight resistant than Persian walnuts and have great commercial potential in the Great Lakes fruit growing region, a climate similar to its native Japan. If only two grafted cultivars are desired, be sure to order an early pollinizer to match with a late pollinizer for best cross pollinization. Go to FAQ for commercial growing information. Winter protect grafted area of the tree for the first 2-3 years in the colder zones of 5b-6a. Seedling trees are suited for zones 4b-7. Tree size can range from 10-15 m (40 ft) in height and spread .
