Plant Bio
Cereus peruvianus monstrose · also called the Monstrose Peruvian Apple Cactus
Another monstrose form of Cereus peruvianus, the Melted Wax Cactus has a slightly different growth habit from the compact monstrose, producing longer, more flowing and wavy irregular columns.
The effect is one of slow-moving, solidified lava or dripped wax — an almost surreal, sculptural appearance that earns it immediate attention in any room. The blue-green body adds to the cool, otherworldly look.
It shares the easy-care, drought-tolerant nature of its parent species, making it as practical as it is dramatic.
What makes it special?
- Longer, more flowing irregular columns than the compact monstrose form.
- The “melted wax” effect is particularly pronounced in mature specimens.
- Grows more quickly than the compact monstrose, putting on interesting new growth each season.
Note: Has reduced but present spines — handle with care. Keep away from children and pets. Grown for ornamental purposes only.
