Since the 70s, the Chickasaw Plums I've seen were small trees, with white to nearly white flowers, and with quite a few fruits. This remains a petite hedge despite the home being uninhabited a long time, the blooms (which look a lot like peach blooms) are cotton candy pink, and I've never seen fruits on it. I'll take pics when it defoliates this winter, and when it blooms in spring. My current best guess is that it might be the root stock of a previously planted peach or nectarine. Crushed leaves exude that "sweet cyanide" scent that I so associate with cherry tree leaves in Denver. I'm hoping someone can help me ID this shrub, thanks!
