I'm a little late to add to this thread, I know there is a list here somewhere of the reblooming daylilies from last year...I just can't find the darn thing
With the short season I get very little rebloom and not many that are consistent year to year.
These three are consistent instant rebloomers and easy for me to remember...
We have a short growing season here too and the early cold weather doesn't allow the later season blooms to open or close properly. Along with instant rebloomers you might also consider budbuilders. Here is a link to a thread about budbuilders....
