Heartnut Seedling Bareroot

Species: Juglans ailantifolia var. cordiformis or hybrid. Our seeds are collected from trees that may have been cross-pollinated by closely related species so the resulting seedlings may be hybrids. 

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 nuts that are sweet than other walnuts and lack the bitter aftertaste. Ideally, they will produce heart-shaped nuts but since they are seedlings they may produce the usual rounder nuts of the regular Japanese walnut. They are sensitive to spring frosts for nut production, so they are best planted in a sheltered location.
