Dollarweed, or pennywort (Hydrocotyle spp.), is a warm-season perennial that is most often found in wet sites. Dollarweed is often confused with dichondra, where the petiole is attached to the edge of a kidney-shaped leaf.
What to look for: green, glossy leaves resembling lily pads
Life cycle: warm-season perennial
Leaves: green, glossy leaves that are round in shape with scalloped edges; a long, slender petiole is attached to the center of the leaf, forming an umbrellalike appearance
Flowers: clusters of white flowers form in summer
Commonly found: in moist to wet sites or anywhere moisture is in excess
Treatment recommendations: minimize irrigation, because most turfgrasses can survive with less moisture than dollarweed can. Apply LockUp® specialty herbicide when dollarweed is actively growing. Repeat spring or fall applications may be necessary, as dollarweed can be difficult to control for an entire growing season.
