Yep, I have one. It's a very hardy succulent that requires very little water (too much will kill it), and grows mighty fast with proper light. In low light, it just sits there, resenting you.
No, I'm kidding.
It just sits there.
Oddly enough, I have one atop my fridge right now. They're poisonous to cats, and I got it before I got my cats, and couldn't find anyone who wanted it. I figured that plunking it up there would do 'for now'. It's sort of like Peter Piper's wife, now. "And there he kept it, very well."
