Pachycereus schottii 'Big Penis Cactus'
Big Penis Cactus
Lophocereus schottii 'Big Penis Cactus'
Pachycereus schottii 'Big Penis Cactus' is a controversial monstrous cactus cultivar with variable, irregularly shaped ribless stems that usually remain small, less than 3.3 feet (1 m) tall. The stems are ascending, lightly pruinose, and also branch just from the base. They mark quite badly with age, due to weathering and old age.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
These extraordinarily low-maintenance plants can basically grow untouched for decades, so there is really not a lot you need to worry about. Obviously, it is very important that they receive adequate sun and heat and be careful around their spines. If grown in containers, make sure that they are being repotted and that their soil isn't too moist. Other than that, these plants are about as simple and hands-off as it gets.
If you do choose to 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, cutting away any dead material from the roots, and replanting. Watch out for the plant's spines, and 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.
