For years, I have seen the yellow fields in Springtime Indiana. Being basically ignorant of botany and agriculture, I mistakenly assumed that the plants were mustard, and in some instances even imagined that they were literal rape (canola) crops.
Today I took the time to walk into a field and pluck a sample of this creature for closer study. Imagine my surprise when at first look I saw not a blossom with four petals, but rather an aster-like cluster of flowers on each stalk. To the interwebz! A Purdue University site quickly made identification certain: Butterweed or Cressleaf Groundsel (Packera glabella formerly Senecio glabellus ).
It’s everywhere! It’s everywhere!
Look at that little dickens. Would you look at that?
