That's cool, mine will most likely be Satsuma, although I used Flavor King on a few flowers, and marked them, so I may grow those out. I didn't protect the flowers, as first I needed to know if anything would work. It doesn't look like pollination is going to be a problem with this cultivar. A very good thing. Satsuma is loaded too. Any cross should be decent. I added three cultivars to my tree, they all took. So Lavina, Loroda, and Spring Satin are grafted unto Nadia. On Satsuma, is Toka, the bubblegum plum, Superior which has American plum in it. May be interesting to add the hardiness, a yellow flesh, a very good large plum. Another yellow is the Vermont plum. Not well known, all reports I have seen say it's excellent.A mango flavor, and a very attractive fruit too, the color is outstanding. Possible crosses may be interesting.
I could lose some of the grafts as they are young, knocked off, broken etc. But I know how to get good takes, so I'll just do it again.
