I did a post a couple of weeks ago on Musk or Nodding Thistle which can be seen here: source
Today I am showing photos of Bull Thistle.
This weed was brought into the U.S. in the early 1800's when the bull thistle seeds were accidentally mixed in with crop seeds. The first year of this plant grows leaves in a rosette at the base of the plant. The second year the flowers bloom from July through September.
The plant has many branching stems, is fast growing and can easily spread along roadsides and croplands. It grows 3-7 feet tall.
I was stooping down to get this photo.
Thanks for stopping by!
