Canada wild plum collection from isolated stands

Canada wild plums, collected from isolated wild stands this week. The fruit is not quite round, a bit elongated and ripens to a yellow/red on the branch and by the time they're fully red they drop. I collect these every year and grow them in the nursery to be able to just get these genetics out there, the trees are considered the best plum pollinator, and it's a bit of conservation for our native plum.
