The list of brown iris which have slowly, or quickly, withered away and disappeared for me gets longer every year. I keep trying them because I think the color is fascinating in flowers and makes a good foil for some of the brighter hues in iris. I'm happy to say that "Buffer Zone" has been a complete success. I wish it were a little taller but it has grown well, bloomed well, and been generally trouble free ever since its first year in my yard. The gold center glow of the petals gives them a "lit from behind" quality and even people who usually don't like brown flowers comment on it. Two thumbs up!
