Have you seen this weed?

Chamberbitter (Phyllanthus urinaria) is a summer annual that germinates from early summer through early fall. This is an aggressive weed that can take over landscape beds and invade lawns. As you can see from the photos, the leaves somewhat resemble mimosa leaves with small bumpy looking fruits under the foliage. Chamberbitter can grow up to 18” tall and will grow in full sun or shade conditions. Early detection and persistent pulling are the keys to controlling this weed. Be sure not to shake the soil from the roots, as that might spread the seeds. Once the weeds have been pulled, be sure to dispose of them in the trash to prevent the spread of this prolific weed.

This is what chamberbitter looks like when mowed along with turfgrass.

Here you can see the small fruit beneath the foliage.
