Common brassbuttons

Common brassbuttons (<em>Cotula coronopifolia</em>) is a small annual or perennial herb with a remarkably broad global distribution, occurring across Africa, Asia, Europe, North America, and South America. This species typically inhabits diverse terrestrial environments, often colonizing wet or damp areas such as salt marshes, mudflats, stream margins, and disturbed roadsides. The common brassbuttons has not been formally evaluated on the IUCN Red List. A member of the family Asteraceae, it produces distinctive button-like yellow flowerheads that give the species its common name. Originally native to southern Africa, the species has spread widely and is considered naturalized or invasive in many regions outside its native range. It often thrives in seasonally flooded habitats and tolerates saline soils, demonstrating considerable ecological flexibility. Biological traits of this species remain poorly documented in the scientific literature.
