Hydrocotyle bonariensis
Largeleaf Pennywort is a fleshy plant, 6–10 inches tall, with round, undivided leaves, 2–4 inches across, attached to the stem in the center of the leaf. The leaf edge is scalloped. The flower head is an umbel 2–3 inches across. Individual flowers are tiny, with 5 greenish-to-white petals. Stems creep and root at the nodes and spreads by rhizomes. Produces a dry dehiscent fruit that at maturity splits two or more parts each with a single seed.
Lives in sandy areas of somewhat extreme conditions, very dry lands that are flooded sometimes. Colonizes sandy ground and disturbed foreshore sites, estuaries, coastline, sand dunes and ponds. H. bonariensis has also displayed a tendency to prefer and be stronger at higher elevations.This one was growing on the beach at Tybee Island, GA.
It is also called Salt Pennywort, Beach Pennywort, and American Pennywort.
