Elaine, I await the results! I've often wondered about this myself. That being said, to get a definitive answer, all four plants would have to be the same cross from the same batch to really prove it one way or the other. I feel the same way about the water issue. All of mine are going on city water, which is chunky here, as my rain barrels are almost empty, and no rain in sight until Oct. The explainations sound sensible, but I have orchids that have lived on city water for over 50 years, and do fine. Andy"s Orchids does put "needs good water" on some of their tags, but only a few, and they don't get any more rain than I do. Even if they have huge cisterns, we got less than 9" of rain this last season, so they wouldn't have been filled. I know rain water is not an issue for you, but my point is that these are tough plants, and if you are a purist, you might adhere to these rules. Personally, I believe the strong survive. I just keep trying to find the survivors.
