Purple Tenacious Flower

On my rural meanderings, I was repeatedly amazed & delighted at the tenacity of various plants in the face of impending winter weather. It’s as if they have a pact to continue about the business of living until the very last minute is insisted upon.
(Watch, someone will point out that this humble wayside flower is actually the scourge of the State, knapweed, whose commitment to its own continuance is a legendary & scary lesson for us all.)
