Broadleaf Weed – Sprawling Horseweed

(Calyptocarpus vialis)

Also sometimes referred to as Straggler Daisy and Calyptocarpus vialis, Sprawling Horseweed is a spreading annual and sometimes perennial broadleaf weed that thrives in lawns and sandy open, disturbed areas, such as pastures, roadsides and waste areas. Calyptocarpus vialis is found throughout much of the southern United States.

Identifying Sprawling Horseweed -

Sprawling Horseweed (or Straggler Daisy) can be identified by its leaves, which have petiole-like bases that are shorter than the blade. It roots at the nodes and can be hairy.

Sprawling Horseweed also features flowers that are yellow and inconspicuous, forming in heads on elongated stalks. It flowers in warm months and reproduces by seeds.

Sprawling Horseweed Control -

Proper cultural practices, such as proper mowing and watering, can help to prevent Sprawling Horseweed by creating dense turf, which inhibits the weed’s ability to grow. Physical removal (i.e. “weed pulling”) can be effective, although you will run the risk of spreading the seeds to additional areas of your lawn.
