I moved to Brooklyn, NY in August and transplanted my healthy Lenten Rose plants from the ground into large clay pots on our balcony. It got really cold this week (low 20 degrees at night) and now all the stems and leaves flopped over. There are flower buds emerging, which still look okay. I am trying to figure out if the plant needs water (it will warm to 40 degrees this week) or the roots were frozen and killed... Thoughts?

These are hardy in your area, and will come back in the spring. You will want to water them less, as they will use less water in the winter months. They will do well, and probably better, if you plant them in the ground. They should recover though. Just let them dry out a little between waterings.
