Etymology: Buttonweed is a plain compound: "button" joined to "weed," so the name describes the plant's appearance rather than telling a story about a person or event. The "button" element refers to the roundish, knob-like heads of the small flowers, which cluster together in a way that resembles the buttons on a garment. "Weed" in this sense is the everyday English word for a wild plant growing where it is not wanted, and it has been used this way for centuries, long before the plants got their common names. The pairing follows a pattern common in English plant names, where a compound describes a visible feature and a general term for a plant. Because the compound is transparent, the name needs little explanation: anyone who has seen the clustered blooms can see why the plant was named as it was.
