I've been growing masdevallias and draculas for many years now and I don't find them as difficult as so many people seem to think. My plants lived through summer heats of 30+C for weeks without showing severe signs of stress. All I did then was to spray the plants a couple of time during the hottest part of the day. Even the coccineas kept on flowering. Most species and hybrids will also tolerate near freezing temperatures as well and I had one last spring that flowered for the first time in 8 years in a pot full of snow. They're tough and I think they ''learn'' to adapt to your conditions in time, as long as people don't try to grow them in constant tropical heat. There are exceptions of course. Some will die no matter what the temperature is.
