I have a sour cherry tree I planted two years ago. It was about 3 1/2' tall when I got it...Maybe 4' tall now. First year it yielded maybe 20 cherries, but I only got 2 because I didn't bother netting it. Last year it produced maybe about a cup of cherries after the pits were taken out. So yes you can get fruit fast, but it is going to have to grow some before its really enough to do something with. I did get a single serving cobbler out of last year's crop though.
I would have to look at home and see if I can find what variety it is. It is a dwarf also.
Seeing that you are in Utah, you might want to do some research on insects...When we were passing through Utah a bunch of years ago we stayed at a campground with lots of cherry trees...Sweet and sour...But they all had worms in them. Not sure if it was the area or what, but just something to be aware of...I am sure you could spray them to prevent it depending on how you feel about chemicals. That is not a problem that my grandparents who used to had a sour cherry tree in Virginia had or one that I have encountered yet in Vermont.
