I collected a small lot from this bush and will grow out the seeds next spring, likely producing similar bushes with a bit of variation, usually these are propagated with softwood cuttings.Read field note +6

canada wild plums hanging heavy on these branches. they're more red where they... - Plum And Cherry Hybrids, August 2026Aug 31, 2026 · Plum & Cherry Hybridscanada wild plums hanging heavy on these branches. they're more red where they get enough sun. the fruit have this distinct elongated shape, larger than the average american wild plum, the trees are less suckering, and the leaves have a less serrated margin. Most of the american wild plum I collected yesterday were starting to fall, or given a shake all of the fruit could be collected for the ground, the canada plums were holding on better ripe yet still firmly attached, maybe this is another typical difference - it's an improvement for the plums to hang on. these trees are in old abandoned tree rows, hanging nearly to the ground, a worthwhile stop on my traveling to collect wild plums for the nursery.Read field note +4
american wild plums, prunus americana. they have a red / green color... - Plum And Cherry Hybrids, August 2026, ASC-256Aug 29, 2026 · Plum & Cherry Hybridsamerican wild plums, prunus americana. they have a red / green color when ripe, more red in the full sun. at the end of august these are just ripe and starting to drop, though there is some variation - another graft has smaller ones that are still green so about a week behind. this is the wild plum I use for interstems on chokecherry, and in fact this is a grafted branch that top worked over a chokecherry tree as the wild rootstock. I'm standing on a short ladder to pick them. this weekend I'll make a trip to collect more wild plums for the nursery, and it's great that we now have some growing here.Read field note +8
