Gamochaeta coarctata, the gray everlasting,[2] is a species of flowering plant in the family Asteraceae. It is widespread in South America (from Colombia to Uruguay) and naturalized in parts of Eurasia, Australia, and North America.[3][4][5]

Gamochaeta coarctata is an annual herb up to 15 cm (5.9 in) tall. Leaves are up to 3 cm (1.2 in) long. The plant forms many small flower heads in elongated arrays. Each head contains 2–4 yellow disc flowers but no ray flowers.[6]

Some specimens collected in the United States were formerly misidentified as G. americana, which does not grow in the United States.[3][7]
