These two need different treatment - the wulfenii has two kinds of stems, those that have flowered this year, and new growth which will flower next year. Cut out all the flowered stems to the ground end of August or September, or whenever they look tatty, leaving the new stems. The other one can have its flowerheads cut off as and when.
