Common ragwort is a hardy biennial that produces bright yellow daisy-like flowers attractive to pollinators but requires careful management. This plant self-seeds readily and can become weedy, so deadhead flowers before seed set if naturalization isn't desired. Thrives in poor soils and full sun with minimal water once established.
