To extend the daylily season(with the exception of re-blooms) six years ago I purchased late blooming daylilies. The season now spans from June 20 to September 14. Perhaps their progany will push it even further. Seeds and time will tell. On a chilly cloudy day this daylily is the last bloom for this season.
Jerry, I have one daylily still blooming at the back of my border. I shall have to figure out what it's name is.
