People much farther inland than I am successfully grow L. anceps outside - low temps very close to, or slightly below freezing more often than I experience them, and summer highs much hotter (and drier) for longer. I think even tougher than Cymbidiums, since L. anceps is also drought-tolerant. When cold, rain protection is good, though - a dry orchid will tolerate a lot more cold than a wet one.

Found the picture that I was looking for... a L anceps growing in a tree in the San Fernando Valley north of Los Angeles (inland, very hot summers, and chilly winters). I don't know how the owner does the watering, I suspect with a hose. This photo is some years old... I recall reading on a forum somewhere that he had a big problem with thieves stealing spikes, in front of his house so not protected from predators.
