Pennywort Identification and Control

Pennywort, or dollarweed, is a water loving perennial that thrives in warm temperate regions.

Pennywort or dollarweed is an aquatic or water-loving perennial that thrives in warm temperate regions. It is a member of the parsley family that was introduced to the Mid-Atlantic region from Asia.

It is a perennial weed that has bright green, rounded leaves with wavy margins. Small, white flowers bloom from July to August. The creeping stems root wherever their nodes touch the soil, increasing the number of plants. Dollarweed grows in moist shady lawns, gardens, and unplanted areas.

What To Do

  • Regular feedings, 2-4 times per year, provide the nutrients your lawn needs to grow thick and strong and help crowd out weeds
  • Mowing at a height best for your lawn allows the grass to grow thick and develop a deep root system. Grass clippings recycle plant nutrients back into the soil.
  • Your lawn will begin to wilt when water is needed. As much as possible take advantage of nature's sprinkler and rely on the rain to water your lawn. If using sprinklers, water lawns deeply and infrequently (1" of water per week is all that your lawn needs).
