Heartnut

Juglans ailantifolia

Heartnut is the heart-shelled selection of Japanese walnut, bred for a shell so thin it cracks easily and a kernel rated among the best-tasting of the walnuts - solving the two things that make most walnuts hard work. It bears unusually early for a nut tree, at three to four years, and is described as the hardiest walnut of all, though it still wants a wind-sheltered spot of its own rather than serving as a windbreak. Like other walnuts, its roots and fallen leaves suppress many plants growing nearby.
