Paper Spine Cactus – Tephrocactus articulatus var. papyracanthus
One of the most distinctive cacti in the world, the Paper Spine Cactus is instantly recognizable by its loose, pine-cone-shaped stem segments and its extraordinary flat, ribbon-like spines — unlike anything else in the cactus family. A slow-growing conversation piece that thrives on neglect, it is equally at home on a sunny windowsill or in a xeriscape garden.

What You Get
4 live cuttings, shipped bare root. Segments may separate during transit — this is completely normal and each separated segment can be rooted independently.
Rooting Instructions
Lay cuttings flat on the surface of dry, well-draining cactus soil — do not bury them upright, as this can cause rot before roots form. The segment may shrivel or curl slightly, but will send out new growth once roots establish. Keep watering to a minimum until you feel resistance when gently tugging the plant (a sign roots have formed). Avoid overwatering, especially in cool or cold weather.
Tip: Handle with paper, not gloves — the barbed spines can catch on fabric.
Frequently Asked Questions
How do I root Paper Spine Cactus cuttings?
Lay the cutting flat on dry cactus soil and leave it alone. Do not water until roots form — usually 2–6 weeks. You’ll know roots have taken hold when the cutting resists a gentle tug.
Why are the segments falling apart?
This is completely normal — the joints of Tephrocactus articulatus are designed to detach easily (a natural dispersal mechanism). Each segment can be rooted individually.
How much water does it need?
Very little. Water sparingly once rooted, and reduce watering significantly in winter. This cactus is highly drought-tolerant and will rot if overwatered.
Can I grow it indoors?
Yes — it thrives on a sunny windowsill with at least 4–6 hours of direct sunlight per day. Use a well-draining cactus mix and a pot with drainage holes.
Are the spines dangerous?
The flat, papery spines are barbed and can catch on skin or fabric. Always handle with a folded piece of paper or cardboard, not gloves.
