Beginner Gardening: Rosettes on Cardinal Flower, 1 by SavvyDaze

Ok this was the first year I grew Cardinal Flowers and I know I must protect the rosettes from the leaves by not allowing them to cover them up over winter. (*Note to self* Don't plant Cardinal Flowers near Oak Trees again!) Anyway, a month ago, my rosettes were full and lush. Since the lower temperature have arrived at night, the rosettes are now somewhat flat. (See Pic) Are they supposed to become flat and perk back up in spring? Or is something wrong with them that is causing them to flatten?

Do I continue to water them until frost or what?

Thanks!
