Nuts Heartnut

Heartnut aka Japanese Walnut

Juglans ailantifolia

An easy-to-grow, spreading, attractive tree with large sweet nuts that halve easily. Abundant foliage, bears early and is hardy. A sweeter, easier-cracking nut than black walnut. A good shade tree with a spreading habit that's prettier in the landscape than black walnut. Susceptible to Walnut Bunch Disease in the deep south. We have grown Heartnuts for 15 years and have not noticed the disease. For the areas of Zone 8 the disease could be more of a problem. Self fruitful 20' to 35' recommended spacing. Zones 5-8.
