Hybridized in 1981 by James Marsh/Roy Klehm, Chicago Apache is a dormant tetraploid that has five-inch blooms and grows 33" tall in my garden. It's a late-season bloomer which is very desirable. Last year's blooms were from July 24 to August 27. This year my plant is huge after all the rain we have had. The scapes have not started peeking out yet, but I'm confident that this season it will put on a show even better than these photos! Chicago Apache is an American Daylily Society award winner as well.
