Yes, we've grown a dwarf peach tree successfully and our only problem is to get to the peaches before the squirrels do. My 2 dwarf apricot trees were mail-ordered from an upstate NY nursery, which (catalogue in hand) I see has a dwarf nectarine tree (matures 8-10' high) and about 6 different varieties of dwarf peach trees. All are "super hardy" which means they survive temps to 25 below zero. If you get your fruit trees mail-order, use a nursery in your own gardening zone (6) or colder, so the survival chances are good.

Peach trees are bothered by a leaf disease called leaf curl. I think it's a fungus, but I'm not sure. My inlaws ended up cutting down their peach tree because of it.
