Which plant is widelt cultivated as an herb, Cotula coronopifolia or Parsley?
Cotula coronopifolia The small marsh flower Cotula coronopifolia bears the common names brass buttons, golden buttons, and buttonweed. The flower heads are bright yellow discoid heads that look like thick buttons. Individual plants spread stems along the ground and send up the knobby flowers at intervals. The plant is native to southern Africa, but it has been introduced to other parts of the world (Europe, North + South America, etc.).
Cyperus articulatus Cyperus articulatus is an aromatic species of sedge known by the common names jointed flatsedge and priprioca. It has also been known as Guinea rush or adrue. It grows as a perennial herb. It grows in water or near it in rivers, streams, lakes, and swamps with a hyperhydrate (emergent aquatic) or possibly tenagophyte (submerged juvenile and terrestrial adult) growth pattern. It is widespread across tropical and subtropical regions in Africa, southern Asia, northern Australia, the southeastern United States, the West Indies, and Latin America. While it is closely related to highly invasive sedges such as purple nut sedge ("Cyperus rotundus"), priprioca is less prolific and competitive than its relative.
