Funny you should ask this question. I was just talking with someone else about these (oncidiums) today. I know in some areas (such as in Florida) these are often grown as outdoor plants and become absolutely huge with thousands of flowers. For me they are one of the most difficult orchids (of the 10-12 genera I grow) to bloom indoors under lights and/or in windows - they seem to grow like weeds, but infrequently bloom - not sure, but I think chances are I am not providing enough light? If your leaves are dark green you might be experiencing the same (just a thought?). Can you also update your profile so that we can see where you live (as janet asks) - it can affect the advice that many will have to offer.
