Another characteristic that is very unusual is that most (if not all) irises will gradually fade in color as the temperatures climb higher and higher. Not this one. As the temperatures climb, the color on the falls of the newly opened irises (of this variety) unfolded with deeper and richer colors. (the color in the standards remained the same). On older flowers that have been opened for a couple of days the colors they originally opened with did not fade either.
You can tell which irises opened as the temperature rose higher and higher with each day. The ones that opened as the tempts rose higher and higher into the 90's - are the ones that have the deepest color in the falls.
