Comments: This cactus is inconspicuous most of the year. When in bloom, it is easily spotted only in the evening and early morning when its spectacular night-blooming flowers are open. It is very popular in desert rock gardens and in the cactus trade; when a population is found in the desert, all too often the large, turnip-like roots are quickly dug up. It can be grown from stem cuttings, if the cut end is allowed to heal in shade for several weeks before it is planted in dry sand. The plant is legally protected in most of its range and should be left in the wild.
