Jim and all of us who have the Chrysler Imperial Roses: these roses should be pruned heavily in February. I have two planted in front of the garage that houses my Imperials. I generally prune them back to 2 to 3 foot stalks each February. This keeps them from going "wild", and also helps keep them healthy. Try it -- they will like it! :o)I know what you mean. They're supposed to be a long stem, single flower variety. After two seasons they went "wild" and turned into a climber with clusters of flowers. Not what I had hoped for, still I haven't had the heart to rip them out.
