Q: I would like to know the scientific name of beggerweed which has 3 leaves, a purple flower and grows about 8 inches tall and how to control it.

A: I believe you are referring to the weed commonly called Creeping Beggarweed whose scientific name is Desmodium incanum. It is found throughout Florida, Texas, Mexico and countries further south. This is a perennial weed with a large taproot and many long extensively branched runners which roots at the nodes. The leaves contain 3 leaflets which vary in size but are generally elliptical and hairy. The stem is erect; flowers range in color from pink to deep rose but are often small and inconspicuous. The fruit forms with six or eight rounded segments which when ripened break off easily and attach to clothing and animal fur. Reproduction can occur by seed, stolons, and broken taproots. It is often found in turfgrass, open woods and disturbed areas.

Use an herbicide for broadleaf weeds, but be careful to read the label and follow instructions. It is important the find an herbicide that will not damage your lawn grass.
