Cereus repandus, the Peruvian apple cactus, is a large, erect, spiny columnar cactus. It is also known as giant club cactus, hedge cactus, cadushi, and kayush. Cereus repandus is grown mostly as an ornamental plant.
With an often tree-like appearance, its cylindrical gray-green to blue stems can reach 10 metres (33 feet) in height and 10–20 cm in diameter as a self-supporting plant.
There are nine to ten rounded ribs that are up to 1 centimeter high. The small areoles on it are far apart. The gray, needle-like thorns are very variable. They are often numerous, but can also be missing entirely. The longest thorns are up to 5 centimeters long.
In the flowering season it produces large cream-white nocturnal flowers, extremely delicate but at the same time showy and remain open for only one night.
Like most cacti they're drought tolerant and need very little care and attention to grow well. Not enough sunlight and over-watering are common mistakes.
Plenty of sunshine will keep this cacti more than happy. In a glass room you may have to provide some shade during a hot summers day to prevent sunburn.
They should be fertilized during their growing season in the summer with a good organic fertilizer.
It is an excellent plant for garden rockery settings, desert type landscapes & Terrariums
