I have a menising weed it is American thissel . It telegraphs along the topsoil and as you know break it off it will self repair and send out just as many new shoots as you broke off . It just finds an opening and grows to about 7’ in about two weeks . The seed pod is about the size of a nickel and highly structured. When mature it has needle like thornes . I have learned not to put this anywhere near the ground . The collages and universities tell you the same thing once you have it you have for ever ,weed control companies stay a way from it , food source for 90 % of the fowl population . Need help !!
