This is a trailing to ascending plant, with bright pink to purple-red flowers. They open in the evening (not necessarily at 4 pm), and close the following morning. The flowers are 5–14 mm across, broadly funnel-shaped, with 5 cleft lobes and prominently exserted, curved stamens. The leaves are fleshy, widely spreading and more or less ovate in shape. Common in more southerly counties, in Monterey this is found in southern Big Sur, and in the extreme east of the County south of the Pinnacles.
