I have experienced that some daylilies in pots aren't getting enough water and nourishment to open the flowers fully, and they do not have the bud count they should have. I do grow in pots some new ones that have come in the mail (not that I have a space problem (grin)). All American Girl (John Rice 2010 - 27 - 5.5) is about to bloom but the bud count is not up to speed.
By the way, unless I say differently, all pictures I post are my own.
