Late wild plums grafted onto chokecherry

collected the last of the wild plums yesterday, this selection (americana #2) ripens about 10 days later than most other wild plums, which is good to spread the season out - they were a solid bright green when the others were starting to drop. this is the first year I've had a crop on these grafts, the last photo shows the union where it's been top worked onto chokecherry. does wild plum graft well onto chokecherry? the answer is probably, though it seems to be about 75% for me, some grafts will fail in the first year. some in the second year can have subtle chlorosis, a yellow tinge to the leaves which is a sign of stress, but most of the time they're perfectly healthy like this one. I find it actually does even better as an interstem. can you just plant wild plums, well yes and long term that's going to work out better I expect, but in this case it was a large choke cherry bush in the yard and I was able to graft over one part of it, if they didn't work out the chokecherry will just rebound from the undergrowth and fill the space back in. it's faster, with a pollinator you're producing plums after one or two years. also in a landscape with dense mature shrubs, planting a seedling right in the mix would suffer for light and be low enough that deer and rabbits can eat it, where grafting at shoulder height solves both of those. so three advantages, plus you get to say your plums grow on a chokecherry tree.
