Description

Lawn burweed, is one of nine species of the Burweed genus in the Asteraceae (daisy) family. It is a small, low, fast-growing, herbaceous, broadleaf annual, typically seen in winter, growing in lawns. It is listed as a noxious weed in several southern states from OR south to CA to FL and north to VA. 

Either full sun or partial shade in stressed, worn, or bare areas of turfgrass is where it grows best reaching height of 2 inches and a spread of 6 inches.  It is known for its tiny sharp-needled seeds and small feathery leaves that have the appearance of parsley. The seeds are contained in a pod that appears in the junction of branches and they can hook onto clothing, shoes or other equipment and travel great distances. The plant develops a number of creeping stems that produce shoots that, if left alone, will form a low ground cover. When the plant matures, it displays small, bright yellow flowers. In some areas of the country, the plants is known as Bindi Patches with the reputation that they cannot be walked on barefoot. This includes dogs and cats, which tend to avoid sites where the weed appears. 

Healthy turfgrass is one of its biggest competitors.  Manually remove the weeds by pulling up the plant including the root; however, this should be done before seeding. Because of its prostrate growth habit, it is very difficult to mow it.  Manage with herbicides that target broadleaf plants. Aerating the soil also tends to reduce the presence of lawn burweed.
