I first came across the sweetpotato cactus ‘Spiralis’ while exploring a local botanical garden. Its spiraling stems immediately caught my attention, and I was instantly drawn to its unique beauty. The name “sweetpotato cactus” comes from the resemblance of its stems to the shape of a sweet potato.
The sweetpotato cactus ‘Spiralis’ is a relatively rare variety, making it even more special for plant enthusiasts and collectors. Its uncommon appearance sets it apart from other cacti, making it a conversation starter and a focal point in any garden.

While these fruits are not edible, they do contribute to the overall charm of the plant.
Taking care of the sweetpotato cactus ‘Spiralis’ is relatively straightforward, making it an excellent choice for both experienced gardeners and beginners. Here are some key care tips:
1. Light: This cactus thrives in bright, indirect sunlight. Place it in a location where it can receive at least six hours of sunlight each day.
