Here is the parent tree, which as I told John, was grafted to FD by Stan McKenzie. I did keep mine indoors during winter for two years before finally planting it outside, but I did protect it last winter. This winter it may be too big to fit under the cover I have.
It almost reaches the height of my fence now.
Pranab, the Rangpur cuttings did not make it unfortunately, otherwise I would have been in touch. Just know that when your wife agrees, I can send you a cutting :)
