Dwarf doesn't necessarily mean small. Here is a picture of my DR, the fence behind is about 5'-8", the p-stem is just over 8'. Started out just under 3', 10 months ago when it went from it's nursery pot and into the ground.
East coast of central Florida, the couple of cold nights this winter (upper 20's and frost) fried the leaves. All the leaves showing are since then.
It hasn't fruited yet but I think soon, but has produced about 8 pups. I think it would be hard to beat for color tho.
