Dollarweed (Hydrocotyle spp.) Also known by some as pennywort, it is a warm-season perennial weed. Its common name, dollarweed, comes from the silver- dollar-shaped leaves that are round, bright green, fleshy and look like miniature lily pads measuring 1-2” in diameter with a scalloped edge. It has a low-growing habit and spreads by seeds, rhizomes and tubers.
Dollarweed is often confused with dichondra. One way to distinguish the two is by looking at the placement of the leaf stem. Dollarweed has a stem located in the center of the leaf while dichondra’s stem is located at the edge. Dollarweed is a water-loving plant that can float. The presence of dollarweed indicates that there is excessive moisture in the area. Research at the University of Florida demonstrated a reduction in dollarweed just by reducing irrigation frequency.
