What is this prickly weed?
Good morning all,
I have spent hours trying to ID this horrible weed in my pasture and growing along every fenceline in Hays Co.
It starts out looking harmless. A cluster of leaves about 4 inches long, rounded ends, slightly serrated edges, and soft grayish green. It then puts on a flower stalk that can be anywhere from 8 to 18 inches long. It puts on a "flower head" that reminds me of a thistle. It then "blooms" with no color and no petals---just horrible tiny spines. It's no bigger than a woman's pinky finger nail. Nothing eats it, not even deer. I've attached a photo of the "bloom". You'll need to double click on it to see it up close. Any help you can provide would be much appreciated.
