As you have probably noticed, I have several dayliles that have Chicago in their name. I have a favorite Chicago daylily and it is Chicago Rosy. It is tall, it is large and it blooms for a long period of time. I don't enjoy dividing daylilies every year, like Stella D'Oro, so I appreciate it when maybe every three or four years I can share my daylilies.
Chicago Rosy is probably a four or five year division candidate, but it is a great performer during this time of multiplying. The flower is large, orange-red in color and has strong scapes that show in all directions. It grows 25 - 30 " with 6.5" flowers. http://seasidedaylily.com/ I have ordered from them several times.
