Like all members of this genus, flowers of sesuvium verrucosum
have no petals, only five sepals, colored rose pink, sometimes tinged with orange. Sepals have minutely irregular edges and pointed tips that curve upwards slightly, and are lanceolate to ovate in shape; they surround a ring of 30 pink, upwards-pointing stamens and a whitish, five-lobed pistil. Filaments are joined at the base, to about a third of their length. Flowers form singly at the leaf axils, and they are generally sessile, lacking pedicels.
The stems and the thick, succulent leaves have a dense covering of tiny, crystalline protrusions. Stems are prostrate, up to 3 feet in length, and branched, forming mats. They do not take root from the leaf nodes.
