Do,you mean the low growing sun roses...helianthemums nadinemc?
Cut back after flowering bht not too hard. Remove flowered stems to just into green shoots below.
Cordylines? You can cut these hard as you like. They will regrow but form multiple stems. Remove/rub out shoots you don't want so you can select how many stems you want and where.
I have a lovely variegated variety that I "play games" with. I let it grow to 12' or so then cut it back. Currently, it is 7' tall approx and multi stemmed. Prob in about 3 or 4 years I will cut it back again
you can do it now or wait until spring
