I bought three single fans of Cosmopolitan in the fall of 2019, and since then this little daylily has been an excellent performer for me in zone 8b and has become a favorite. The three fans have increased to nine since then, and it has been a prolific bloomer. This year (2021), it started blooming on March 30, and today (July 19), it is still going strong with a few buds left to open.
Scapes have been the regulation 18" for me, and the plant has not had a speck of rust (knock on wood). This one is a keeper. It apparently does well everywhere! I recommend it for those who appreciate a small, pretty bloom standing well above its healthy foliage.
