The columns often have a gray-green or bluish tint in full sun. There seems to be some genetic variation in coloring, and color is more pronounced on new growth.
During the warm months of the year, large, 8-inch diameter, greenish-white flowers will open at night. They have a delicate fragrance, and pollinated flowers will develop an edible fruit that turns pink or red when ripe.
Some Cereus are self-infertile, so if you're growing these for the fruit, try to obtain more than one genetic strain for cross-pollination.
This plant is sometimes also called Peruvian Apple or Night Blooming Cereus. They grow well in containers and will flower and produce fruit if given adequate light.
