american wild plums, prunus americana. they have a red / green color when ripe... - Plum And Cherry Hybrids, August 2026Aug 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
black ice plums, perfectly ripe on Aug 20. first time trying these, on... - Plum And Cherry Hybrids, August 2026...Aug 20, 2026 · Plum & Cherry Hybridsblack ice plums, perfectly ripe on Aug 20. first time trying these, on some grafts made just last year. they flower early like other sand cherry hybrids. tasty, similar flavour to a black plum from a grocery store, better of course because they're perfectly ripe still at the beginning window, the skin is darkening quickly, and it's is good - with just a subtle tartness for balance. for a prairie plum, these are excellent for the size, precocity, and flavour. Many of the plums in our collection are on new grafts and i'm still waiting to try them, these were a treat this summer. Shown here they're growing on a grafts about head height onto wild plum interstem, on a chokecherry rootstock. nearby a lower graft was broken by a foraging deer, so the high graft offers wildlife protection and maybe also from the cold, often it's a few degrees warmer up there.Read field note +4
