Arizona's "Queen of the Night," the night-blooming Cereus cactus, photographed by Carl Hankwitz, early on the morning of June 4, 2008, in the Dos Lagos subdivision on Dove Mountain. Typically all the plants in one area will open at one time. Filling the air with a heavy perfume, they attract large numbers of pollinating insects. The flowers close soon after dawn and do not re-open the next night. The flower produces a large red fruit that also is sweet and edible. Most flowers only bloom one night a year.
