200 year-old house on 25 rocky acres in high country upstate NY and SO many highbush blueberries!
I'm certain it's a Prunus, just a matter of what kind. May be a cherry, especially because of that glossy bark with the white dots, but it could also be a plum of some kind. Most cherry trees get taller than these little guys, but there is a dwarfy-shrubby kind called Nanking cherry that is pretty small. I thought it was interesting that there was fruit on them in the fall (is that right? That's what it seemed like). That's what's making me think maybe it's not a cherry but a plum. How fun to have these little botanical mysteries unfolding. Do you have fireflies yet?
Yes, it had fruit on Sept 20 last year when I first saw this house. Although I live at 1800 feet (nothing for you, high desert person), so this may be equivalent to end of August at the Hudson River elevation of 200 ft. The fireflies started a week or so ago. Do you have them at all? My sister in Oregon doesn't have them, so her daughters had a ball when they came east and saw their first fireflies a few summers ago.
The fireflies are out here in northeastern Minnesota - have been for just over a week. They seem early, though: last year I didn't see the first one until July 1st!
No, no fireflies here. :-(
