Introduced from tropical America, wedelia was a widely used groundcover, popular for its daisy-like flowers and fast growth habit.
Wedelia has golden flowers that can easily be mistaken for beach sunflower. Unlike beach sunflower, however, wedelia has become a threat to many native plants, spreading out beyond landscapes into natural areas. A member of the sunflower family, wedelia forms a thick mat of vegetation that crowds out other plants and blocks light to existing plants.
It is now listed by the UF/IFAS Assessment of Non-native Plants in Florida's Natural Areas as invasive and should not be planted in any region of the state. Don’t plant wedelia in your landscape, and if it’s already present, consider removing it. The plant is extremely sturdy and can survive drought, freezes, mowing, and heavy shade. For the university's latest control recommendations please contact your county Extension office.
