Bushy Buttonweed


Found in warm, humid climates of most continents, as well as Hawaii, the West Indies, and from Florida to Louisiana. Considered a native in the U.S., but also found throughout Latin America and in Asia.


An annual weed reproducing from seeds. Plants flower throughout the warm months. These are many-branched weeds with thin, weak stems that tend to grow prostrate along the ground or through turf, making them tolerant of low-mowing and difficult to remove physically.


Stems are thin and potentially very long, with few or no hairs on them. Leaves are opposite and are elongate oval with sharply pointed tips and a sharp base on a short petiole. The spacing of the leaves is very close, almost giving the impression of a 4-leaved whorl on the stems.

Characteristicts Important to Control:

Preventive control in turf or landscape with pre-emergent herbicides, and post-emergent control in turf with a selective broadleaf herbicide.
