Another juglans native to N. America, as with most walnuts grafted trees are critical for large crackable nuts. Black walnut shells are very hard, these cultivars a bit more crackable and nuts more readily extractable.
A sunny site with deep well drained soil will produce a fast growing tall tree. They can be self-fertile but best to plant two or more.
