Dollarweed Weed Killer

Hydrocotyle verticillata Herbicide

Description of Dollarweed (Hydrocotyle verticillata):
Dollarweed is also known as pennywort. Despite the name, dollarweed is a free weed you can find in the lawn. Like dollar spot fungus, it gets its name from being shaped and sized similar to a US silver dollar. The best way to explain the appearance of it, however, is that it looks like miniature lily pads in a sea of turfgrass.


Other common name: Pennywort
