I found this pink sand verbena blooming trail side in Torrey Pines State Park. The pink color in contrast with the beige sand is eye catching.
From the UCI website A prostrate perennial with succulent leaves (but thinner than in A. maritima), found as a carpet-like ground cover on beaches and sand dunes from British Columbia, Canada to Baja California, Mexico. It has no petals but instead 5 showy pink tubular calyx lobes which are flared at the ends and deeply cleft. There are three stamens and one pistil within the flower tube.
