Canada wild plum comparison and nursery seed source

a comparison of Canada wild plums. the center one (and group in the front in the last photo) is the wild collected plums that we know are just pure and unhybridized, the best representation of the species in the group. the left ones are an old planting, the ones we collect for our seed shop. they're open pollinated in an old tree row, slightly smaller plums but the shape and color and the leaf morphology gives them a strong Canada plum identity, the right one is from an old orchard row with other wild plums, and likely it has a bit of hybridization, but you know there is genetic variation in the species, there are selections like Assiniboine and Patterson Pride that have larger fruit.
