Oenothera caespitosa is very common perennial in dry lower to middle elevation plains and hillsides. It has large white petals that turn pink with age. The anthers are large and the stigma stands well above them and is 4 parted. The leaves are crenate to lobed and gray green. The plants are acaulescent (have no stem.)
