I am looking for a small flowering tree for my back yard. It needs to be no more than 15 feet tall as I'm trying to grow veggies fairly nearby.

Yesterday I stopped at my local garden center and they had a new tree. It was a dwarf ornamental pear tree. It looked to me like a mini Callery pear. Same basic shape with similar flowers/leaves. They said it would get no more than 15 feet tall and would be narrower which is good for my garden. I actually like the bradford/callery pear trees. I know they are overused and prone to breakage but they are still pretty to me so I was kind of excited to find a dwarf version that would actually fit in my yard.

Does anyone know anything about the dwarf ornamental pear tree? I think it had the name "jack" in the variety.
