Looks like a wild black cherry to me. It may not be old enough to have cherries yet. They're good for making jam and jelly.

I think you are right!!! That is pretty cool!

Wow it is a fast grower! I think it has done all this growth in 3 yrs. I found a pic of lumpy grass area from cut down bamboo and in the background you can see the cactus where the cherry tree is. I zoomed in best that FB would let me and the tree is not visible.

If you want it to be bushier so you can harvest the berries, lop about half that height off in February so it will branch out. Keep the branches pruned back to about a foot long to encourage branching and it will be a nice, bushy tree that will eventually give you plenty of shade.

I wouldn't prune a cherry tree like that. At least not one that wasn't an orchard cultivar on a dwarfing root-stock, in a fruit production area setting.

In fact I wouldn't subject any kind of tree that I wanted to develop into a shade tree or other normally developed specimen to such treatment.

It looks just like one of our wild cherry trees. Only ours is pretty tall, too tall to try to prune. I've never seen fruit on ours or any others around here. I don't know if the birds get it first, but I've never seen flowers, either. Same for the wild grape vines. But our leaves are beginning to turn, too, it's one of the first signs of fall around here, along with the beauty berries. It's also the first tree to get new leaves in the spring.

I was reading it can take about 10 yrs before it bares any fruit, that it has to be mature enough and you can tell it is mature once the bark changes.

I am a little sad to hear the bark will change, I really like the look of it right now.
