- Description
-
Soliva sessilis, or Lawn Burweed, is one of nine species of the Burweed genus. It is a small, low-growing, herbaceous, broadleaf annual, typically seen in winter, that can be weedy or invasive. It is listed as a noxious weed on the databases of 46 states. 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 in the junction of branches. The plant develops a number of creeping stems that produce shoots that, if left alone, will form a low ground cover. If the plant is allowed to mature, and not be removed, it does display small, bright 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.
You can manually remove the weed by pulling up the root; however, this should be done before seeding. It can also be controlled with herbicides that target broadleaf plants. Aerating the soil also tends to reduce the presence of Lawn Burweed.
