Know before you buy
No, this plant is not considered pet-safe. It is best kept in a location that is inaccessible to cats and dogs due to its sharp spines and potential toxicity if ingested.
This cactus prefers bright, direct sunlight. A south-facing windowsill is ideal, though it can tolerate bright indirect light as long as it remains consistent.
You should only water when the soil is completely dry throughout the entire pot. Because it is drought-tolerant, it is safer to underwater than to overwater, which can lead to root rot.
Use a specialized, gritty cactus or succulent potting mix. These blends are designed to provide the excellent drainage necessary to prevent moisture from sitting around the roots.
Yes, with enough bright light, it will produce vibrant magenta flowers during the spring and early summer months. Ensure it receives plenty of sun during the growing season to encourage this display.
