I wish I could say that I know what I'm doing, but really I'm just trying to do my best.
I have this beauty by an east window (it gets bright light from about 8:30 until about 1) I water once a week by running slightly warm water through it. I haven't changed it from the pot I originally bought it in. Looks like moss, bark and charcoal.
Maybe this time around I'll remember to take a picture of its beautiful white flowers.
