Pansies protect themselves by allowing moisture to escape their leaves as temperatures fall. Other plants cannot do this, so when the temperature goes below freezing the water in their cells freezes and ruptures the cell walls. That’s what happens when you leave a houseplant on the patio during a freeze. Dry cells, though, can’t rupture. They just go limp. It is normal to see pansy leaves completely wilted at dawn but green and perky by noon. That’s why it is important to keep the soil in pansy beds moist after a freeze…. so their roots can rehydrate the leaves.
