Botanical Name: Tephrocactus articulatus var. papyracanthus
Common Name: Paper Spine Cactus
Tephrocactus articulatus var. papyracanthus, commonly known as the Paper Spine Cactus, is a slow-growing, highly sculptural cactus prized for its distinctive flattened, papery spines and segmented growth. Native to the arid and semi-arid regions of western Argentina, this unique species naturally grows on the lower slopes of the Andes, where it thrives in dry, open landscapes with excellent drainage. It forms small clumps of articulated segments, typically reaching a mature height of 6–12 inches, with some specimens growing slightly taller under ideal conditions. Its unusual texture and compact form make it a standout addition to any cactus collection.
Care and Cultivation:
• Full sun to bright light for best growth
• Well-draining cactus or succulent soil; sandy or gravelly mixes preferred
• Water sparingly using the soak-and-dry method during the growing season
• Extremely low maintenance once established
Frost Tolerance and Cold Hardiness:
• Hardy in USDA zones 8b–10b
• Can tolerate brief temperature drops to 15°F (-9°C) if kept completely dry
• Sensitive to prolonged freezing or cold, damp conditions; protection recommended
Winter Dormancy and Health:
• Naturally winter-dormant
• Reduce watering drastically or stop entirely during dormancy
• Keep soil dry to prevent rot and cold damage
