Well, I am going to blow everyone out of the water. I plant my roses (not climbers) 12 to 18 inches apart. Anything with spacing of 2 feet is very far apart for me and there are not many of those.
There are somethings that go along with the way I have my garden set up. I have dug up and given away perfectly good roses that were space hogs and did not want to play nice with their neightbors. Thinking of Austins Golden Celebration and Falstaff for instance. And l prune very heavily each spring. Very heavily. Then I also prune down again after the spring flush but not as much as in the spring. That gives me another strong flush in August. After that I let them be and just cut spent blooms. So they keep blooming until frost. I leave them tall going into winter as I feel it is better for winter hardyness.
I have some HTs, many, many floribudas and also roses that get lumped into the shrub rose catagory. I also do have some that I let get large and are anyway from the main rose beds.
