I have always considered them warm growers. I guess the definition of "warm", "intermediate" and "cool" is in the eye of the grower. I cannot imagine successfully growing orchids in the heat and humidity that we have in our region if they don't love the heat. Perhaps "love" is not a good term. "Tolerant" may be a better term. Bert, don't you grow your Cattleya alliance orchids outside during the spring, summer, and early fall?
