Common Names: Green Cathedral Cactus

Overview: Step into the world of architectural elegance with the Green Cathedral Cactus, a sculptural masterpiece that brings the desert’s timeless beauty right into your home or garden. This striking cactus captivates with its multiple, columnar arms arranged in a tiered fashion, resembling the intricate spires of a cathedral. The deep green hue of its skin adds to its visual magnetism, making it a show-stopping centerpiece in any space.

Perfect for both beginners and cactus aficionados, the Green Cathedral Cactus is remarkably easy to care for. Thriving in well-drained soil and requiring minimal water, it’s a low-maintenance marvel that’s hardy and resilient. It prefers full sun but adapts well to partial shade, growing to heights of 6-15 feet when fully mature—although smaller, potted versions are available for indoor enthusiasts. This desert gem also blooms with small, whitish flowers in season, adding a subtle touch of color to its awe-inspiring structure. Make a lasting impression with this dramatic, yet fuss-free, botanical marvel.

Sunlight is essential for all cacti, and the Cathedral Cactus is no exception. They thrive best in full sunlight when outdoors. If indoors, position it near a south or west-facing window where it can receive ample sunlight. If the cactus starts to look elongated or discolored, it may be a sign of insufficient light.


Like most cacti, Cathedral Cacti prefer well-draining soil. Use a cactus mix or create your own with one part potting soil, two parts coarse sand, and one part perlite. This combination ensures that excess water drains quickly, preventing root rot.


Overwatering is a common mistake with cacti. Cathedral Cacti are drought-tolerant and have adapted to survive in arid conditions. In spring and summer, water once the top 1-2 inches of soil feels dry to the touch. In the dormant winter months, cut back significantly, watering only when the soil is completely dry.


Cathedral Cacti are warm-weather plants. They flourish in temperatures between 70°F and 100°F (21°C to 37°C) during the day and prefer a drop of about 10-15 degrees at night. While they can tolerate minor frosts, prolonged exposure to temperatures below 50°F (10°C) can harm them. If you’re growing your cactus outdoors in a cooler climate, consider bringing it inside during the colder months.


While not heavy feeders, Cathedral Cacti benefit from a boost during their growing season. Use a cactus-specific fertilizer diluted to half-strength. Fertilize once at the beginning of spring and again in mid-summer. Avoid over-fertilizing as this can lead to overly rapid growth and a weak plant.


Generally, Cathedral Cacti require minimal pruning. However, if there’s any dead or damaged tissue, it’s a good idea to remove it to prevent potential diseases. When handling your cactus, always use protective gloves or wrap it in layers of newspaper to avoid the spines.


Cathedral Cacti can be propagated from seeds or offsets. Offsets are the small cacti that grow at the base of an established plant.
