Appears to be native tree. Some sort of plum but would like specific. Zone 8 I believe.
Hi Rebecca,
yes, this is certainly a plum, and most likely a cultivar, not a native species. It does not match our more common wild one, American plum – Prunus americana. All are in the genus Prunus, along with peaches and cherries. I do not know the cultivated plums, I’m afraid. This site, however, will give you a lot of information to the various kinds: http://www.michiganplum.org/plum-variety-descriptions/
