Buartnut: Exploring the Unique Nut Hybrid

Buartnut, a fascinating nut hybrid, combines the best qualities of three nut species: the butternut, the heartnut, and the Japanese walnut. In the world of buartnuts, we look at their characteristics, cultivation, and availability for purchase. Discover the allure of this unique nut and how you can incorporate it into your garden or orchard.


Buartnuts are the result of crossbreeding the butternut tree (Juglans cinerea), the heartnut (Juglans ailantifolia var. cordiformis), and the Japanese walnut (Juglans ailantifolia). This hybridization process combines the desirable traits of these nut species, resulting in a nut with a sweet flavor and a thin shell, making it easier to crack and enjoy. Buartnuts are an exciting alternative to traditional nuts, offering a distinct taste and texture.




The buartnut tree (Juglans x bixbyi) is the tree that produces the buartnuts. It is a hardy and adaptable tree, capable of growing in a wide range of climates and soil types. These trees exhibit characteristics inherited from their parent species, such as disease resistance from the butternut and heart-shaped nuts from the heartnut. These trees typically reach a height of 30 to 40 feet and produce an abundant crop of buartnuts once mature.
