I'd have to say I was very surprised after I'd dug up Betty Warren Woods last year and gave it away for not having ever bloomed (otherwise a great daylily I really want in my garden!!). I'd left the spot bare as I was going to order a fan from a different seller than had supplied the original. But, this spring a new fan of it popped up in the old spot! It is very healthy and thriving ... but still no bloom yet. Just for the fact that it showed up again, I'll wait for a maiden bloom till end of summer ... then we may go into a "groundhog day" scenario of digging up and meeting again the next spring of every year!
