Botanical Name: Tephrocactus articulatus var. papyracanthus
Common Names: Paper Spine Cactus, Paper-Spined Tephrocactus, Jointed Cactus
Tephrocactus articulatus var. papyracanthus is a unique, clumping cactus native to northern Argentina, recognized for its segmented, jointed stems covered in papery, whitish spines. This slow-growing, architectural cactus forms clusters of small, cylindrical joints that can reach 6–12 inches tall each. Its unusual appearance and compact growth habit make it perfect for container cultivation, rock gardens, and succulent collections.
Care and Cultivation:
Prefers full sun to bright light
Water sparingly; allow soil to dry completely between waterings
Use a fast-draining cactus or succulent soil mix
Excellent for containers, xeriscapes, and rock gardens
Frost Tolerance and Cold Hardiness:
Best suited for USDA Zones 9–11
Can tolerate brief cold down to about 25°F (-4°C) when dry
Protect from prolonged freezing and excess winter moisture
Ideal growing temperatures: 65–90°F (18–32°C)
Winter Dormancy and Health:
Growth slows during cooler months
Reduce watering significantly in winter
Maintain bright light to promote healthy joint development
Notes:
Distinctive papery spines give a striking architectural texture
Forms segmented clumps over time
Drought-tolerant and low-maintenance
Perfect for container displays and rock gardens
