For those of you who grow tall bearded irises in hot and humid climes, you may be interested in what Evey recommends:

"I am often asked about which bearded irises I enjoy growing. I am a big fan of many of the irises hybridized by Walter Moores. Though I am sure there are successes all over the country, I personally know of gardeners who have enjoyed growing Walter's cultivars in Washington, California, Colorado, Texas, Kansas, Tennessee, Ohio, New York, Georgia, Mississippi, and Louisiana (yes, Louisiana!). He has registered almost 90 cultivars over the years, but I now limit my recommendations to those that have won AIS awards (Award of Merit or Honorable Mention) and his more recent cultivars (registered 1999 or later). I also recommend some older cultivars that didn't win an award, but have special qualities that attract me. Unfortunately, it has become increasingly difficult to find his cultivars offered in commerce, so I have created a list of sources to give out as a reference when anyone asks, "Where can I get that one?" Below is a list of the cultivars I would recommend growing and where you can find them (last updated June 5, 2013). If you know of additional sources for any of these, please let me know!"
