Potted Heartnut Seedling
Potted Heartnut Seedling
Available only for pick-up at nursery.
Species: Juglans ailantifolia var. cordiformis
History: Heartnuts are a sport of the Japanese Walnut that have a heart-shaped shell and kernel instead of the usual elliptical shell. They have good commercial potential in the Great Lakes area where the climate is similar to that of Japan.
Why We Grow It: These trees produce an abundance of tasty heart-shaped nuts that are sweet than other walnuts and lack the bitter aftertaste. They are sensitive to spring frosts for nut production, so they are best planted in a sheltered location.
