4" Horrid Spine Cactus

Horrid Spine Cactus (Gymnocalycium horridispinum) Horrid Spine Cactus is a compact, eye-catching cactus known for its rounded, deep green body and its intimidating, sharply protruding spines that radiate outward in dramatic patterns. The strong contrast between the smooth, sculptural form and the aggressive-looking spines gives this plant a bold, desert aesthetic despite its relatively small size. It’s an excellent choice for collectors who appreciate unusual texture and classic cactus character. Slow-growing and extremely drought-tolerant, this Gymnocalycium thrives with minimal care and bright light. Care Tips:☀️ Light: Bright light to full sun; a sunny window is ideal💧 Water: Water sparingly; allow soil to dry out completely between waterings🌫 Humidity: Prefers low humidity❄️ Temperature: Thrives in warm temps (65–90°F); keep above 40°F🐾 Pet Friendly: Yes (with care—spines are sharp) Fun Fact:The name horridispinum literally means “terrible spines,” a fitting tribute to this cactus’
