Description
Lophocereus schottii 'Big Penis Cactus', formerly known as Pachycereus schottii 'Big Penis Cactus', is a slow-growing cactus with ribless, irregularly shaped, gray-green stems covered with a fine, waxy bloom. The stems are usually upright, branching from the base, and can grow up to 3.3 feet (1 m) tall.

How to Grow and Care for Lophocereus schottii 'Big Penis Cactus'
Hardiness: USDA hardiness zones 9b to 11b: from 25°F (-3.9°C) to 50°F (10°C).
These extraordinarily low-maintenance plants can grow untouched for decades, so there is not much you need to worry about. However, they must receive adequate sun and heat and be careful around their spines. If grown in containers, ensure they are being repotted, and their soil isn't too moist. Other than that, these plants are about as simple and hands-off as it gets.
If you cultivate a small specimen in a container, repotting it can be helpful. If so, repot it as you would any other cactus by removing it from the pot, removing any dead material from the roots, and replanting. Watch out for the plant's spines, as they can really ruin your day.
Like most cacti and succulents, these plants propagate by cuttings. Sever a branch and replant in well-drained soil. Make sure to stand the cactus up in an empty container to let its ends heal off before you replant it. This will keep its stems shaped right, and cacti with dried ends form roots more easily after planting.
