Frost damage on Skunk Cabbage plants

 This picture shows how Skunk Cabbage (Symplocarpus foetidus) plants should look right now.
 

 

The next picture shows how they actually looked yesterday morning.

Several nights of heavy frost have badly damaged the leaves of the plants.  Hopefully they can recover.
 

It amazing to me that the plant's flowers can melt snow due to the metabolic heat that they generate,

but the leaves can be damaged by a few hours of freezing temperatures.
