Thorn bush with red berries in Arizona - Rhamnus crocea

I've been finding lots of these cropping up on my land in the last year or so, but I dont know what they are. Before I transplant some I'm hoping someone can help. I originally thought they might be wolf berry but now I'm not sure. They get tiny red berries on them around late summer or fall but I've never seen flowers.

Pics are from mobile, hopefully they're good enough quality.

(upload didn't seem to work so I put one if the pics on my website)

I would guess some sort of lycium species.

They remind me quite a bit of pyracantha--

it may also be Rhamnus crocea.

The leaf size and bark color are wrong for pyracantha, in my opinion.

The pyracantha leaves look much longer and thinner. The leaves on this are similar to purselane. Spoon shaped and fleshy. They're smaller than the fingernail base in my pinky finger.

Some Desert-thorn and wolf berry labeled images online look close but not quite. Will look up the other names suggested here and see what I find.

Hopefully, you will be able to get some flower pictures this year.

Steve, the crocea pictures and info look very promising, thank you!

I suspect most of them have been dormant due to drought but I've been doing a lot of water harvesting and that may have been what made them start putting on leaves and berries. I was thrilled when I found them but I dont want to mess with them if they're dangerous. I found jimson weed/datura last fall and while beautiful I don't intend to touch it or put it into my primary food areas. Hopefully this one is more friendly

I have Rhamnus crocea growing on my property. They are edible, with a bitter sweet flavor. I have not experimented with them very much. Hopefully you will be able to get a positive ID. I wish you the best!
