Broadleaf Weed – Thymeleaf Speedwell

(Veronica serpyllifolia)

Also known by its scientific name, Veronica serpyllifolia, Thymeleaf Speedwell is a perennial broadleaf weed that can be found in much of the eastern United States as well as in several northwestern states. Thymeleaf Speedwell thrives in moist to wet environments, including woods, slopes and hillsides, grassy areas and waste areas.

Identifying Thymeleaf Speedwell -

Thymeleaf Speedwell is identified by hairless, laterally growing stems and leaves. The weed roots at the nodes when they are in contact with the soil and form dense mats. This is especially evident when the weed is living among turfgrass. Thymeleaf Speedwell also has a fibrous root system.

Thymeleaf Speedwell features purple and white flowers that are deeply lobed or notched at the tip. It can be distinguished from Mouse-ear Chickweed by the lack of hairs on the stem.

Thymeleaf Speedwell Control -

Proper cultural practices, such as proper mowing and watering, can help to prevent Thymeleaf Speedwell 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 and landscaping.
