I found this plant while poking around the lake. Hubby was fishing so I was just doing the photograph thing. I'm not as smart as I look though, I used a Photoshop action from Coffeeshop called "cross processing" I had no idea what the flower was, so I did a little googling. My google-fu is strong and I found this information on a Missouri conservation website. Score!
Although tall and
straggly, with leaf points ending in sharp spines, Tall Thistle
produces an attractive tufted lavendar flower. Seeds are carried by the wind on a downy white "parachute". The seeds are prized by goldfinches, who also use the fluffy down to line their nests"
