Name: Michele Roth N.E. Indiana - Zone 5b, and F (Zone 9b) I'm always on my way out the door..
Their stems may have been more hardened since they were up for longer than a day before the frosts hit. Just guessing here, but it seems plausible anyway. Mine were newly emerged, and I'd think still tender as the dickens; however, I just checked on it and it's trying to recover. Midway down the stem was where it was blackened and crunchy, but now it just looks scuffed a bit...and it's straightened back up. Yay!
Queen of the North is my favorite daffodil today. She's s in a shadier location, and still she stands so straight and proud!
