Butternut (juglans cinera): The white walnut. Fast growing tree with tasty, buttery, thick shelled nuts. Pure butternut trees are susceptible to an introduced fungal disease known as butternut canker. Our trees are grown from seed from healthy parent trees that are likely to be wild hybrids between butternut and Japanese walnut. Extremely hardy walnut to zone 3/4
Carpathian Walnut (juglans regia): This is the walnut that resembles those we see in the store. Thin shelled nuts. Trees are hardy to zone 5 and best planted in sites with good air drainage as they have a tendency to flower early in the spring.
Black Walnut (juglans nigra): Very tough trees, grown for nuts or timber. Black walnuts have an unrivaled flavor that is loved by some and disliked by others. They are considered excellent by almost everyone when tasted in baked goods. Our seed source is only trees grown in upstate NY with apparent resistance to nectria canker. We select seed from trees with excellent timber form.
Heartnut Seedling (juglans ailanthifolia): These are japanese walnuts, one of the most beautiful shade trees. The compound leaves are huge and tropical looking. The trees have an open spreading form. They grow fast and produce copious clusters of delicious walnuts that taste a lot like a butternut, but are much easier to shell, especially with a quality nut cracker.
We see Japanese walnuts as having the most potential for a commercial walnut in the Northeast.
