Dollarweed also known as pennywort, is a warm-season perennial weed. It gets the common name, dollarweed, from its silver- dollar-shaped leaves. The leaves of dollarweed 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 that spreads by seeds, rhizomes and tubers.
