Herb Robert Geranium robertianum
This Class B non-designate noxious weed is widespread in western Washignton. Control is recommended, but not required in King County.
Herb Robert escaped from ornamental plantings and thrives in forested communities as the dominant ground cover, displacing native and beneficial plants.
Herb Robert's 5-petaled flowers are in all shades of pink and sometimes white. Overall the plant is covered with short glandular hairs, giving the plant a sticky feel and a distinct odor (sometimes this plant is known as "stinky Bob"). Shallow, weak roots make this plant easy to pull although large infestations can be highly labor-intensive to remove.
Program offices are located at 201 S. Jackson St., Suite 600, Seattle, WA 98104. To contact a staff member at the King County Noxious Weed Control Program, please call 206-296-0290 or by reach them by email.
