Weed ID

Asked April 8, 2020, 5:29 PM EDT

I planted a new yard last fall, and this spring I’ve found this plant (see picture) growing all over in the grass. Any idea what it is and the best way to get rid of it?

Hi-
From the picture, this weed appears to be redstem filaree. It is a winter annual or biennial that spreads by seed. Stems are a few inches to up to a footlong, is spreading and grows from a basal rosette. Leaves and stems are hairy. Flowers are pink or purple.

Here is a link to more information: https://www.colorado.gov/pacific/agconservation/redstem-filaree. If weed is not widespread you may wish to remove the weed by hand. The most common herbicidal control for broadleaf weeds in the lawn is 2-4, D. Please read and follow all label directions for safe use and application.
