Burweed, or Spurweed, is a low-growing, cool-season, annual broadleaf weed. It is easily identified by its low, fernlike foliage and sharp, spiny seed pods, which ripen in late spring. The leaves are deeply divided and covered in fine hairs. The stems branch at the base and have dark purple spots.
Burweed comes up in the fall from seeds deposited the previous spring. It grows slowly through winter, flowers and sets seed again in the spring. It then dies as temperatures warm up in late spring.
Burweed is found in mild winter climates of the Southeast and Southwestern United States.
