I like this question because I am trying to add longer blooming daylilies. I'm going to have to check out Paper Butterfly. Most of my daylilies only bloom 3-4 weeks, except the ones that bloom a while, rest a while, and come back and rebloom, like Stella, Black-eyed Stella, Happy Returns, Stella's Ruffled Fingers, etc. Here are some of my blooms that have averages around five weeks for the last three years or so for me. A lot of them are "bud builders".
Final Touch (7.1 weeks)
Uncle Bryan (6.2 weeks)
Pardon Me (6.1 weeks)
Howdy (6.0 weeks)
Mascara Snake (5.7 weeks)
Resident Alien (5.4 weeks)
Crazy Awesome (5.4 weeks)
Frans Hals (5.2 weeks)
Foothills Fantasy (4.9 weeks)
Late Report (4.9 weeks)
Dyna Girl (4.8 weeks)
Sunny Intervals (4.5 weeks)
