Punkdoc, I always break the rules
flowerlover, i cut this one very hard leaving hardly a discernible leaf. Then clean the area. This prevents caterpillars having a nibble and creates fresh foliage in a very short time
have to say though that I decide on a plant by plant basis....for example, one Rozanne is not cut back and it makes an attractive wide (10') mound of flowers all summer. this one though makes few flowers in autumn so a choice to make.
