Tempesto is beautiful! It has a lot of color and yet is still mellow. I'll bet that will make a gorgeous clump! Some irises have a wonderful bloom but sometimes an iris that is not your favorite single bloom makes the most awesome clump. Sometimes an iris will make a healthy clump but needs to be grown by another clump in order for either of them to take your breath away. Later we may have to start a thread about the merits of which iris make the loveliest clumps and why. I know a lot has to do with an individuals taste but...... I wonder if most people seem to be attracted to the same attributes of an iris clump...... interesting.....
