If you are having light problems as well, I recommend a 5000k fluorescent bulb. People will recommend the 6500k as well because they're even stronger, but they put out an almost blue light and I've heard from a reptile lighting company that they believe this spectrum of color is a little harsh for chameleons, turning everything sort of gray in their eyes. A 5000k produces more natural light, for both us and them, and my plants were doing pretty well when I had them.
I've had success with ficus, scheflera, and pothos. I've tried gardenia, hibiscus, bougainvillea, and a couple others and they just don't do well. Not everything can be an indoor plant, unfortunately!
