Tephrocactus articulatus var inermis


Tephrocactus articulatus var inermis grow in an architectural, pinecone shape with thin jointed limbs. The plant has evolved to propagate through division, dropping whole limbs at the weak joints to root wherever it falls. Careful of the glochids that grow at the areoles as they can be irritating if handled without gloves.

Please note: Every plant will vary in size, color and shape from the one pictured. Plant ships bare root. Soil included according to plant size.

Native to Western Argentina.


These cacti prefer lots of sun, at least 5 to 8 hours of direct sun daily. Indoors a south facing window is ideal. Outdoors place them where they will receive plenty of sun exposure, but protect them from intense, peak afternoon sun. Bring it inside if winters are cold and wet.


In the summer months, water only when the soil has dried out completely. Always err on the side of underwatering. They are built to withstand drought, and overwatering is one of the quickest ways to kill them. Water less in the winter months and only when there is a stretch of sunshine in the forecast.

Tula's Tip

The Tephrocactus will turn a blue/green to purple color when grown in full sun. The blooms last only one day and grow from the cactus crown. Blooms are more likely if the plant gets a chill over winter. Fertilize: The Tephrocactus does not require fertilizer though it can be added to give container grown plants a boost or to supplement poor soil. Apply a water-soluble, balanced fertilizer monthly, diluted at half strength.


The 4" pot version is Approx 4" tall, and the 6" is Approx. 21" tall x 5-6" at the widest point. Every plant will vary in size, color and shape.
