Asiatic coinwort is a small creeping herb with shovel shaped leaves emerging alternately in clusters at the stem nodes. The runners lie along the ground and the inch long leaves with their scalloped edges rise above on long reddish petioles. The insignificant greenish- to pinkish-white flowers are borne in dense umbels (clusters in which all the flower stalks arise from the same point) on separate stems in the summer. The seeds are pumpkin-shaped nutlets 0.1-0.2 in (3-5 mm) long. Coinwort grows in sunny damp places like wetland edges, roadside ditches, and soggy lawns. It seems to prefer somewhat disturbed areas where the sandy soils have been heavily enriched with organic matter.
