I have had Osterized in my garden for about five years it does very well here in zone 4. I will have to pay attention this year to check for poly blooms. Guess that tells you I have lots of daylilies and am not always as observant each and every day. I do love the clump when it is in bloom.
I also copied Judy's information in a file and will read it when I have some extra time.
