I would like to get some recommendations on good dwarf flowering plum trees. I currently have two Crater Vesuvius trees in my back yard that just grow way to fast, and I'd like to replace them with smaller varieties. In addition, to control the size of the Vesuvius trees, I need to give them a good trim during the winter dormant season, but new growth shoots up vertically giving the tree an odd straight up form.

I prefer a tree that remains smaller (10-15 feet) with a round shape, or if you trim it, new growth will NOT be vertical so that the tree retains it's rounded form.

I actually have seen a very small variety in my area (San Francisco Bay Area), but most trees look diseased, with many dried out branches, and I'd like to avoid that variety, whatever it is. I've also seen another slightly larger variety with a rounded look that looks much healthier, and that's the one that I prefer to get, but not sure which variety it is either.

Any recommendations will be greatly appreciated.
