I’ve posted a few times about my experiment of some years wherein I grafted a prune plum to nanking cherry rootstock. It took off and grew, but took seven years to bloom, and now, in its eighth year had only a few blossoms. The blossoms didn’t impress me and I didn’t expect any fruitset. But I was wrong- there’s two on it now. The root sucker that I planted from the same clone at the same time is behaving about the same- it’s got one plum hanging.
So for now it’s working. I’ve got a severely dwarfed prune plum producing, well, kinda, and looking healthy. We’ll see how it does in the next few years.
Kinda of a hoot in any event just have it do this well. Stay tuned.
