Red leaves on the base I would guess Citation Rootstock. That is the one I had blow over but it's tough. The Burgundy plum that blew over in the tornado, one of the pictures I text you, that one is on Citation. I stood it back up by hand, staked it, and pruned some sail weight out of it (opening it up more) just look at the fruit hanging off one year later. All the Pluots & Plurreys I have is on that rootstock too. Loves Jobe fruit tree spikes.
