Other info. - This species is easily recognized by the strong glaucousness of all parts of the plant, its thickened, succulent leaves, and white flowers. As is common with members of this genus, the flowers are fully open only in the early morning, closing by noon, especially on sunny days. The plant seems partial to barren mine tailings, surviving in this harsh environment which supports little else.
