Chickasaw Plum 'Guthrie'

Got this from Mail Order Natives. It is a lovely native plum that has sweet golf ball sized fruit. The fruit is yellow often with a red...Read Moredish blush. It is a small tree that blooms prolifically and serves as a pollinator for other plums. I wouldn't be surprised if this was a natural hybrid between common Chickasaw plum and a Japanese or European plum but, if so, it maintains most of its native characteristics, including the ability to do well on its own roots. I've taken a number of cuttings and they produce nice identical trees. I'm experimenting with growing out the seedlings since the only other plum in my yard is a commercial large-fruited red plum that could possibly have pollinated the Guthrie flowers. If it pollinated itself I guess the worst I can get is a common Chickasaw plum which isn't a bad deal either.
