Actually Prunus mahaleb is frequently used as grafting understock for commercial culinary sweet and sour cherry propagation. You never see it offered to retail market, as fruit is not as tasty, and it flowers are not quite as spectacular other flowering cherries available in the USA. But it's disease resistance is good, and it tolerates a wide range of soils. Cut off or kill off the scion part of a sweet cherry and odds are fair your understock is P. mahaleb.It's growing strong! I don't really see them here in N.America, but I like all that I have seen from Europe.
It's the same in Europe. They grow wild but of course is mainly used as grafting under stock. Not many people use it as bonsai because as you say we also have some other varieties with bigger and more spectacular flowers. It doesn't heal well from cuts and instead it creates dead wood. People who use this vsriaty for bonsai, do it mainly to enjoy the interesting dead wood. Mine doesn't have this characteristic yet developedActually Prunus mahaleb is frequently used as grafting understock for commercial culinary sweet and sour cherry propagation.

Hello,Is it grafted? It looks like there are two very different bark textures. I have two sweet cherry trees I plan to air layer next year that I know have P. muhaleb as their rootstock, and the rootstock has bark like the lower half of your tree. The upper half looks like what I would expect from sweet cherries or ornamental flowering cherries. But then the flowers on the top look like photos I've seen of P. muhaleb. So idk. I'm no expert, just very curious.
It's not grafted. I believe the upper part will get similar to lower part with some time
