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 30cm in height. Has rounded stems up to 40cm long, rooting at nodes and with the flowering stems ascending. Leaves are fleshy, hairy, 4-9cm long and 2-5cm wide, serrate or irregularly toothed, normally with pairs of lateral lobes, and dark green above and lighter green below. Peduncles are 3-10cm long; involucres are campanulate to hemispherical, about 1cm high; chaffy bracts are lanceolate, rigid. The flowers are bright yellow ray florets of about 8-13 per head, rays are 6-15mm long; disk-corollas 4-5mm long. The pappus is a crown of short fimbriate scales. The seeds are tuberculate achenes, 4-5mm long. Propagation is mostly vegetatively as seeds are usually not fertile.
It has a very wide ecological tolerance range, but grows best in sunny areas with well-drained, moist soil at low elevations.
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.
