This weekend should provide ample opportunities along with perfect weather to do a bit of botanizing and enjoying nature in general. I suggest you go for the gold: Marsh Marigolds. A walk in my favorite woods produced my favorite spring sighting- a babbling brook with a thriving community of Marsh Marigolds,Calthapalustrisand Skunk Cabbage, Symplocarpusfoetidus.
See if you can locate these early of the spring wetland plants in your area. They are a heartening sight after a long winter!
