i have a few vandas growing on my balcony outdoors all year long in southern california. i have a few blues, and they take our winter pretty well, and i have a few others also that seem to be doing well. i bought all of them small sized and some are now getting to blooming size. any of the vandas from the himalaya region do well here, and so do many of the hybrids from them. i wish i had more space... i would get a ton more of them.
