Buartnut - Pierce selection
This is a cross between a Butternut and a Heartnut, Juglans cinerea x Juglans ailantifolia.
These seedlings exhibit the strongest growth we have ever seen; probably a result of hybrid vigor. These hybrids have the intense hardiness of the Butternut and the precocity (nuts in clusters of 10-15!) of the Heartnut. The nuts are exactly like a Butternut.
