Much like the United States Postal Service, these plants will not let rain, nor sleet, nor driving snow stop them from pulling through the worst winter weather imaginable.  It can be hard to find plants that will look two months of drying winds in the eyes and laugh—or sit in a frozen puddle for 4 months and not rot.
