Clustered Mille Graines grows on the wet shores of ponds and lakes, on the banks of rivers and streams, in swamps and marshes, in bogs and seeps, in wet flatwoods, around waterfilled depressions, and in wet roadside ditches. It is an annual with a tap root. The stems are erect to ascending, green in color, angled, loosely branched, and pubescent with white hairs. Leaves are opposite, sessile to subsessile, lanceolate to ovate in outline, pubescent to nearly glabrous, with entire margins. Flowers are clustered and sessile in the axils of the leaves or terminal. Each flower has 4 pubescent green sepals. The corolla is white with a short tubular portion and 4 spreading lobes.
