Gamochaeta calviceps is a small annual herb in the daisy family, native to the southeastern United States and South America, with narrow leaves and clusters of tiny purple flower heads. It is a weedy plant of fields and disturbed ground rather than a garden ornamental, so it is grown mainly by letting it self-seed or for wildlife interest.
