Hi all, I'm new to gardening, and also to allthingsplants. I would like someone to explain why my 6 y.o old daylilies changed in 2012 from the beautiful mixed colors I ordered, to pale yellow. Still lovely, but I liked with I ordered. 2013 they didn't bloom at all, So, far this year, they haven't even grown. Do daylilies have a life span, even though I divided them?
thanks
