canada wild plum, or p

canada wild plum, or p. nigra cross. upright tree form, double bumps on the leaf margins, thin point in the leaf. seeds will be hybridized since it was in an orchard next to american plums, but still a good find, stratifying these in the root cellar. really wasn’t sure until reviewing the photos, good to photo document a find. #wildplum #prunusnigra
