Tick-weed is a common term used to describe a weed that typically grows in grassy areas where ticks are prevalent. While this term is frequently used, there are other synonyms that can be used to refer to the same plant. These include ragweed, groundsel, and tansy ragwort. Each of these terms refers to a slightly different species of plant, but they all share the same characteristics as the tick-weed. Using these various synonyms can help to provide more clarity when discussing these plants, and can also help to prevent confusion between different types of weeds.
