Submitter has sample
EDRR Status: Local expert notified
Tall, thin stems with narrow leaves, and branching near top with thistle-like flowers, purple, with shape like Bachelor's Button (another Centaura). There was quite a bit of it along the guard rail. Earlier I had reported some around the electric station just a bit east of there, and they have done a thorough job of mowing that, so I don't know if that will take care of it for long, but at least they are making some effort.
