This is a great performer for me in dry high desert, Prescott, AZ. I do not water. After wettish winter my 4 year clump has 9 stalks about 4 feet tall. Ready to open like tomorrow. I love this historic and would recommend as it seems tough. I like tough performers. Not into babying or watering.

Back in the 1950's my mother had many iris. However, out of them all, this one and Wabash were my absolute favorites. This one was simply huge, and smelled like concord grapes. I always looked forward to seeing it bloom.

William A. Setchell [Dolly Madison x Purissima] Brehm, 1938 Historic TB 36" scapes ML bloomtime. Giant Gargantuan, and Mammoth is what describes this Violet-Blue Self iris, with heavy branched stems. Very similar to 'Lent A. Williamson', not as tall of scapes, and larger, huge blooms. Some people do not like its billowy, flowing form, and they claim it lacks rigidity and substance, I however, thinks it adds to its striking and vivid color, on it's lovely, haunting and flowing, giant blooms.
