Origin
Stenocereus beneckei f. inermis is a spineless form of Stenocereus beneckei.
Description
Stenocereus beneckei f. inermis is a shrubby cactus with bluish-green or bronze-green stems with 5 to 9 tuberculate ribs and a white waxy coating. Its white, almost spineless stems can distinguish it from the typical form. The stems are erect to decumbent and can grow up to 6.5 feet (2 m) long and 3 inches (7.5 cm) in diameter.
The night-blooming flowers are narrowly funnel-shaped, grayish-white, or cream-colored, appear in winter, and can reach up to 2 inches (5 cm) in length.
Hardiness
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Like most cacti, Cereus are fairly low-maintenance and hardy. Ensure they receive enough water without becoming waterlogged, especially during the summer, and fertilize them for the best results. If the roots have become black or overly soft, the cactus could be experiencing root rot. Cut away the affected parts and replant them. Most gardeners interested in cacti should be able to cultivate these without much problem.
If your Cereus outgrows its container, it may become necessary to repot it. If so, make sure the soil is dry, and then remove the pot. Knock away old soil, prune away any rotted or dead roots, and then replace it in a new pot and backfill it with fresh soil. Ensure not to overwater cacti planted in new pots, as this can lead to root rot. It should be left dry for about a week and then watered lightly.
These cacti propagate quite easily from cuttings. Simply sever a branch and replant in moist, well-drained soil.
