seems to me that daylilies can be pretty unpredictable. Apart from blooms on a single plant changing appearance across the day, they seem to sometimes respond to environmental conditions and show diversity. Like SPACECOAST RUFFLES doubling only on its last rebloom. And the polypetalling after some combination of rain and shine. Some of my plants have had very Extended blooms, but only some of the time.
I have plants like MARCIA FAY which are registered as Semi Evergreen, but every June the leaves all die off and healthy new ones shoot up. Others registered as Dormants like GRAND MASTERPIECE keep all their leaves in winter here.
I hope Sabrina that you never get rust in your garden. MILDRED MITCHELL is beautiful but I will be giving it the RAGP (remove all green parts treatment) before I plant it from its pot into the garden.
