When I saw this one I had to have it. The tag say grafted 4.17.15. Its only a bit over a ft tall. To me the leaf size is comparable to 'Junhitoye'. But we will see how the tree reacts in my care.
I'm all for not pushing JM's and letting them grow slow, but wow, that is very surprising for seven years old! No fear of soft bark and wood from growing too fast, lol.
