I have seen Louisiana irises come and go for more than 50 years. I have seen not-so-good ones make it to the top and then disappear from gardens. But worse than that are the really excellent varieties that have never received awards nor become generally known. What makes the difference and what can a hybridizer do to elevate these good ones from the ordinary to the winner's circle? Nothing I am going to suggest will be news to you and some solutions will not be possible, but perhaps one or two will give you an idea. Each are things I have observed and some are things I know have worked for some Louisiana iris winners in the past.
