On inland dunes, open swaths of sand provide habitat for sunloving annual plants and low-growing desert wildflowers such as white evening primrose, pink sand verbena, and violet locoweed. In the troughs between the dunes (interdune areas), you'll find scurf-pea and "blowout" or bunchgrasses, and at dune edges, taller shrubby plants like creosote bush, four-winged saltbush, honey mesquite.
