Mary, although ragwort, or tansy ragwort is sometimes called ragweed, it isn't the same as what most of us call ragweed.

Giant Ragweed, Ambrosia trifida is a perennial with palmate leaves bearing three to five deeply cut lobes. (also known as blood ragweed, great ragweed, horseweed, perennial ragweed (great), tall ragweed)
