Cotula coronopifolia is a perennial herb that is not native to California.
[Cal-IPC] South Africa native, Invasive: Cotula coronopifolia (brassbuttons) is a perennial herb (family Asteraceae) found along the coast of California, in the Central Valley and the South Coast Ranges. Brassbuttons prefers moist habitat, including salt and freshwater marshes, wetlands, and vernal pools. It most commonly invades disturbed sites, but can spread into undisturbed sites as well. This South African native has flat yellow flower heads that produce small seeds, which are distributed by moving water and birds. Its stems grow roots at the nodes, allowing the plant to reproduce vegetatively. Although brassbuttons is known to be invasive, its spread appears to be relatively slow.
