Can't mistake the fragrance of the Dame's Rocket

We visited a huge wetland near Wellsboro recently with the hopes of photographing some new species of ducks.  While that didn't seem to happen for us, we were treated to the fragrance of a large patch of nearby flowers.  These flowers are called Dame's Rocket and are one of my wife's favorite wild flowers.  They are often confused with Phlox but there is one major difference.  Phlox has 5 petals while the Dame's Rocket is always 4.  The smell of these small fragile flowers is something you will look forward to every year and means nicer weather is upon us.
