Bought this from Norman Orchids (orchids.com) 2 years ago. They profess to grow this outdoors here in So. California. The first year I did that no flowers, now I grow it a little warmer (min 65F/18C) I got a crop of six nicely scented flowers. I water it like a Cattelya, I think they resent being constantly wet, so I let it dry out quite a bit. The potting medium consists of very course bark, charcoal and clay pallets (hydroton).
p.s. as a bonus, it has a very nice musky/lemony scent.
Enjoy
