Q.non-flowering campsis
planted a campsis tagliabuana (madame galen) in autumn 2013 against south facing wall where i expected it to be very happy. it has grown very strongly each year since and is a great shape and self clings brilliantly. cut it back reasonably hard each year and it goes away freely next spring. BUT IT WILL NOT FLOWER. is there anything i can do or should i start again. thanks for your help.
