From what I have read they are.
The first winter I did a ton of research on how to keep my plant alive, it is sentimental. The best solution was to mimic a mild winter. So I put them under low sun lamps 8 hours a day and try to keep them at 68 degrees. Unfortunately I was too scared to freeze, burry or anything else. They don't bloom, so I assume they are in a semi hibernation, but they keep their leaves.
Here is a picture, sorry the image isn't the best. But the silky webbing and white critters means spider mites right?
