Cirsium arvense

{{Argicultural pest | common_name = Creeping thistle | latin_name =Cirsium arvense | image =Cirsium arvense bluete.jpeg | caption = | range =Native throughout Europe and northern Asia, and widely introduced elsewhere. | description =It is a tall herbaceous perennial plant, forming extensive clonal colonies from an underground root system that sends up numerous erect stems each spring, reaching 1–1.2 m tall (occasionally more); the stems often lie partly flat by summer but can stay erect if supported by other vegetation. The leaves are very spiny, lobed, up to 15–20 cm long and 2–3 cm broad (smaller on the upper part of the flower stem). The inflorescence is 10–22 mm diameter, pink-purple, with all the florets of similar form (no division into disc and ray florets). | control = This plant is extremely difficult to control, as it can regrow from fairly small root fragments and is resistant to many herbicides.
