Does anyone know what this is? A friend gave me a start of it about 2 yrs. ago and while it hasn't died, it hasn't grown either. Hers is huge and blooming and everytime she asks me how mine is, I have to fudge a little. She's in Duncanville, and I'm in Tyler and chances are she'll never be here, but I need some help! This needs to grow. Anybody ever heard of it? I never had.
