I have several that have taken a while to bloom. I bought tet Holly Dancer 3 years ago and am still waiting for a scape, also My Heart Belongs to Daddy 2 years ago. Both were bought on eBay and I have no idea if they were mature fans or not, however they are both looking very healthy and I am hoping for a result this year.
I bought Mount Echo Sunrise 2 years ago from someone I trust and it has not bloomed until now, even though the fans were large. I also bought from the same seller 3 years ago Patchwork Puzzle which refused to bloom. The seller told me to move it - even a couple of feet and it bloomed. I planted another daylily in the original place of PP and it bloomed immediately!
I have no idea why one would happily bloom in a specific place while another sulked.
