Nice pic, looks like they have a little bit. The leaves look rather strange to me... That being said, i live in SE Ok as well and really need to find myself a sand plum patch.

Edit: looked it up, that is a mexican plum.

Here are other pics

The Mexican plum fruit turns from green to a sort of yellowish-orange color first. Then they turn a deep reddish-maroon with a white bloom on the skin when they are ripe. (Bloom on fruit is that whitish coating that looks like a light dusting of powder or chalk.)

The color change is easy to recognize when you see it, but can be hard to describe and a photo is worth a thousand words, so I found a webpage that shows 3 photos in a row that show the color change I described. I hope it helps.

Folklore says that for the best jelly, you should wait for the fruit to fall off the tree. I don't do that though. I do wait and pick it when it is the right color and soft. Gently squeeze a green fruit and note how hard it is. Then, after the color begins changing, do that again. The fruit will be softer. Then, when it is at the color that looks ripe to you, squeeze it again. It should be fairly soft compared to how hard it was when it was green. Taste a couple of the ripe ones and see if they taste ripe. Then, if they seem ripe to you, pick more. Don't pick them all because you think they are ripe and then taste one and realize they weren't ripe yet because you cannot put them back on the tree. (grin)
