I am not an expert, but as noted in a couple of threads they do like it on the cool side. I learned this by experience with a couple I picked up for Renee out of the discount basked at the grocery, something like $1.50 each. They lasted a couple of months and then finally sucumbed once the weather started to get too warm. A friend at church has one similar to the white one above that has been in bloom and thriving for her for many years. She is going to start one for us to try. Next time I visit I will try to remember my camera and snap a picture.
