Another "what Is This Tree"?

The plant pictured could also be a common chokecherry (Prunus virginiana), which common traits include suckering and fruiting profusely, and is commonly found throughout the woods in Missouri and beyond. The plant in the photos is certainly in the Prunus Genus, which includes plums and cherry trees & shrubs. Not as commonly planted in urban and suburban landscape plantings, mostly due to other available plants with somewhat better characteristics.

This tree is in my orchard along with apple, peach & pear trees. I have noticed many sprouts in the area, mostly on the edges

I still think it may be crabapple. Take a fruit and cut it open down the middle. If it has one single stony pit inside it is a wild plum, if it has several little seeds in a core then it is crabapple.

It looks like a plum to me. Let them ripen and they are pretty tasty.

Fax me one of the fruit, I'll eat it , and tell you what it is.

It has one seed or pit. I try one every weekend & they are getting sweeter. My work has crabapple trees near our lot, these are nothing alike.

Juice them and make some jelly. I gave a bunch a few years ago to a lady and they came back to me in jars of jelly.
