I live in Bethesda, just a 10 minute drive from American
University where your wife studies and a 15 minute drive from
Georgetown Medical School. The winter around here was VERY harsh,
indeed. I hope you didn't lose too many plants. If your Sarraceniae
were mulched under leaves then they should be okay. Rob Sacilotto
informs me that his plants survived nicely, and in Stanardsville, VA
he had lower temperatures than we did.
