Campanulata will grow in warm intermediate conditions just fine. Oddly enough, some of the 'not-swampy-conditions' LL will work great in that too like pervillei and clipeata. So like tshirt and shorts weather during the day and tshirt and jeans weather during the night... maybe long sleeved shirt if you're used to it being really roasting 
For every plant looking nice, I have another that is not too great. Its a constant struggle for me to keep everything happy. Sometimes I have found some species to thrive that only later on start to decline suddenly upon no reason. All I can suggest is lighting, air circulation and decent humidity.
