My mom thinks it's a Mirabelle plum tree (Prunus domestica), but those appear to produce orange plums. It's in southeastern Idaho, gets full sun from about 9 AM until sunset.

What do you think?

    Is the color of the ripened fruit green or are you referring to fruits in its early stages? Most fruits start out green and turn a different color only when they ripen Oct 17, 2011 at 2:51

    @KirkHings Are the mature fruit round or oval in shape? When you wash the wax coating off of a mature fruit, what colour is the skin? Approximately how tall is the tree? Can you describe the taste of a mature fruit? Can you please post a photo of a mature fruit cut open so we can see the colour of the flesh inside...

  • These pics taken just two days ago, so I'll have to wait for them to ripen (if they do anymore this year-most things are done for the year in SE Idaho). The tree is about 20ish years old, about 16-20 feet tall. I haven't eaten one, my mom said it isn't the greatest plum but not terrible either. I'll check on these questions though.

    Doh! She always called them green plums for years, and now admits they turn orange at the end. Unless someone can prove otherwise, I'll give a thumbs up to an answer of mirabella. Oct 19, 2011 at 19:53

Immature Mirabella is the probable answer. I'm posting it here to clear this question from the unanswered list.

Other possibilities based on the picture would be Damson plums or immature Satsuma plums (image).
