This reminds me of several years ago when we had a warm spring with no freezing temperatures for weeks and then had a severe freeze on Easter morning. The daylily foliage looked like "boiled cabbage" and had to all be cut back. It was another job that I did not need at a very busy time of the year, but one that had to be done.
Fred, your daylilies look amazing! Like Leslie, I am jealous!
Your garden will be a showplace for the region tour in a few months.
