We're nearly neighbors... Costa Mesa here. Cuitlauzina pendula grows outside very nicely in our area. I suggest a basket, so that it drains well. It certainly needs to hang so that the spikes can hang over the side. The plant should be potted high enough that the pendulous spikes that come out from the new growth can get to the edge of the basket (they come out pretty much horizontal, then droop over the side). A side note... the spikes are pendulous but they are not flexible. They are actually quite brittle. (I learned this the hard way
) Give the plant a little love (and water) and the blooms are some of the prettiest in orchiddom.
