Sphagneticola trilobata, commonly known as the Bay Biscayne creeping-oxeye, Singapore daisy, creeping-oxeye, trailing daisy, and wedelia, is a plant in the Heliantheae tribe of the Asteraceae (sunflower) family. It is native to Mexico, Central America, and the Caribbean, but now grows throughout the Neotropics. It is widely cultivated as an ornamental groundcover.Spreading, mat-forming perennial herb up to 30 cm in height. Has rounded stems up to 40 cm long, rooting at nodes and with the flowering stems ascending. Leaves are fleshy, hairy, 4–9 cm long and 2–5 cm wide, serrate or irregularly toothed, normally with pairs of lateral lobes, and dark green above and lighter green below. Peduncles are 3–10 cm long; involucres are campanulate to hemispherical, about 1 cm high; chaffy bracts are lanceolate, rigid. The flowers are bright yellow ray florets of about 8-13 per head, rays are 6–15 mm long; disk-corollas 4–5 mm long. The pappus is a crown of short fimbriate scales.

Invasive Species

• Invasive[1.침입하는
• 2.침략적인 3.간섭하는]

Sphagneticola trilobata is listed in the IUCN's “List of the world's 100 worst invasive species”. It is spread by people as an ornamental or groundcover that is planted in gardens, and then it is spread into surrounding areas by dumping of garden waste. It spreads vegetatively, not by seed. It rapidly forms a dense ground cover, crowding away and preventing other plant species from regenerating. This species is widely available as an ornamental and is therefore likely to spread further.

It is a noxious weed in agricultural land, along roadsides urban waste places and other disturbed sites. It is also invasive along streams, canals, along the borders of mangrove swamps and in coastal vegetation.

It is widespread as an invasive species on the Pacific Islands, Hong Kong, South Africa, Australia, Indonesia, and Sri Lanka.
