Bristle Thistle
This plant is native to Eurasia, and is considered a noxious weed in Colorado. It grows in open areas such as meadows or along the roadsides. Despite its spiky appearance and unwelcome presence, it is quite pretty. The top is a bright pinkish-purple color and soft to the touch. The lower section of the flower is spiky, either green or purplish. The beauty of this plant is its perfectly spiraled symmetry.
