- Other Names: Field burrweed, Onehungaweed, lawnweed, jojo weed, common soliva, bindi weed, bindii, bindi-eye
Origin:
Native to South America, and now found along the Pacific Coast states and along the southern states to North Carolina, as well as throughout Latin America and in Europe.
Biology:
A winter annual growing in a prostrate, spreading habit. Reproduction is from seeds. Small flowers appear if the plant develops.
Identification:
Very similar to spurweed. Low growing and prostrate, and with numerous stems radiating outward from the central base. Leaves are opposite and twice divided into narrow lobes. The flowers are green, small, and inconspicuous, and clustered in the axils of the leaves. They produce seeds that are flat and armed with sharp spines that can be quite painful when stepped on. Seeds also tend to cling to clothing.
Characteristics Important to Control:
Pulling the plant at the root when its started to flower but before developing seeds. It can also be treated with herbicide when the plant is weakest in the late winter/early spring. MCPA and Dicamba tend to be the most effective herbicides. The plant thrives in compacted ground, so aerating the soil also reduces its growth.
