Heartnut (Juglans ailantifolia)


SKU: N/A Category: Tag:


Heartnut is a genetic mutation of the Japanese walnut. The mutation produces a flattened, Valentine-heart shaped nut which cracks and releases the kernel easily. The kernel is the sweetest and mildest-tasting of all the walnuts. Heartnuts are variable, but tend to be precocious and heavy bearing, and preliminary indications suggest they may be resistant to Thousand Canker Disease.

Our heartnuts did not set a crop in 2020. We will not have potted trees grown from seed available for summer of 2021. We have a small quantity of heartnut trees that grew in pots 2020. We will make these available as bare-rooted or potted trees Spring of 2021 until they are gone.

Not all heartnut seedlings will grow into trees that produce heartnuts. Many will “revert back to wild type” and produce only the normal Japanese walnut, which is rounded, thick-shelled, difficult to crack, and commercially worthless. It may be necessary to plant several to get a single good one. Quantities are limited. 12 – 18 inch tall seedlings in 9 x 4 x 4 inch pots. Zones 5 – 6. No quantity discounts.

Potted or Bare-rooted Seedlings $6.00
(Available potted, bare-root April – June?)
