I wonder if some dormants try to protect themselves from the warm weather by pulling their roots down deeper? I think some daylilies just can't take the hot summers and warm winters, I don't think they even need to necessary be a dormant. It just seems that sometimes no matter what certain plants start out great and over a couple of years just diminish to the point of non existence. Sometimes that happens rather rapidly, and I can't even to began to guess the real reason.
