Hawaii Native Status: Introduced. This naturalized ornamental flowering groundcover is native to Mexico and Central and South America.
Flower Color: Yellow
Height: Usually under 1 foot (30 cm) tall
Description: The solitary flower heads are 1 inch (2.5 cm) across and have yellow, 3-notched rays and yellow disks. The rays are either solid yellow or tipped with paler yellow. The leaves are fleshy, green, very shiny, irregularly toothed or serrate, and narrowly egg-shaped. Some of the leaves are tri-lobed with a pair of smaller side lobes. The plants are creeping and mat-forming, and the stems take root at the nodes.
Here in Hawaii, Wedelia grows wild in open, disturbed areas at lower elevations, where it can form a dense groundcover and crowd out other low-growing plants. The plants spread by the rooting stems and occasionally by seed.
