The plant forms a thick, cylindrical body covered in prominent golden to reddish spines arranged in regular patterns across blue-green skin. It grows as a solitary barrel that can reach 3 to 5 feet tall in its native habitat, though container specimens remain much smaller. The stem deepens in color under bright light, shifting toward greenish tones in shadier conditions.
Small yellow flowers bloom near the crown of the plant in late spring to early summer, appearing in clusters along the upper portions of the stem. The blooms are followed by yellowish fruits that persist on the plant for an extended period.
You can leave it up to ten days without water. Move it outside for summer to encourage stronger growth and deeper spine development. It is pet-friendly and safe around cats and dogs. Keep it on a high shelf out of reach of toddlers, as the sharp spines pose a hazard for small children.
Ferocactus viridescens grows best in direct sun but tolerates low-light indoor conditions for extended periods.
Water it every 2 to 3 weeks during the growing season, allowing soil to dry completely between waterings.
Ferocactus viridescens does best in fast-draining cactus or succulent soil mixed with extra perlite or coarse sand.
It prefers temperatures between 50°F and 85°F and tolerates dry heated air from heaters and air conditioning without difficulty.
