(Juglans ailantifolia)  A sport of the Japanese walnut with a thick shelled but easily crackable, usually heart shaped nut that is sweet and mild. Trees are fast growing with huge compound leaves and foliage so abundant they look almost tropical. It is extremely hardy, growing 20 – 30 ft. high and thrives in most soils. They mature faster than other nut trees, usually bearing in 3 to 5 years. It produces nuts in clusters, sometimes as many as 10 per cluster. Technically they are self-fertile but they will set a larger crop if you plant 2 seedlings.
