Wildlife Spotting

(That quote was from the provided link in the ID, btw...)

Even though this is considered an invasive, it's still an interesting plant. "The dried flower heads were attached to spindles, wheels, or cylinders, sometimes called teasel frames, to raise the nap on fabrics (that is, to tease the fibres).[6] By the 20th century, teasels were largely replaced by metal cards, which could be made uniform and do not require constant replacement as the teasel heads wear. However, some people who weave wool still prefer to use teasels for raising the nap, claiming that the result is better; in particular, if a teasel meets serious resistance in the fabric, it will break, whereas a metal tool would rip the cloth."
