I think I have it as well, it's doing well by me. I am growing it under a 50% shade cloth hanging out in the over head covered open all year around. It took last winteer well here.
So. Calif. San Fernando Valley, I do fertilize it often, it has not set flowers yet, it will probably need more sun to do that.
We also grow it at the Huntington Gardens, I didn't know that was it's name. I thought it was a Rhipsalis. Now I have a name for this plant. Norma
