The tree is approxiamtely 16 years olsd from a seedling. It is finally starting to bear, but I have only one tree. I had to wrap the one nut in mesh to prevent tne grey and black squirrels from getting it. The nuts look amazingly like an English walnut. Tree is hardy here in the 4b zone. I wish that I had planted numerous ones now!

After six years of growth Fall of 2006 was first year for limited production (six pods on three trees). Trees have attained height of 15-18 ft. with trunks 6-9" in diameter. Pods began to spit the third week in September. Nuts have been collected and need to dry out/cure as they have not yet developed full flavor. Trees are easy to grow and produce waxy dark green foilage, ideal for shade. Must prune suckers early on and then only as needed.
