Ariocarpus furfuraceus forma mostruosa
 

.

.

Cultivation: The plants of this cultivars are often grafted to accelerate growth as they are extremely slow growing on their own roots, but the grafted plants are typical rather tall growing, compared with plants on their own roots that are usually more flat to the ground. The plants need deep pots to accommodate the napiform unit formed by the stem base and the rootstock (or they will often simply crack your pots),  and a loose mineral soil with a well-drained substrate. They need a good amount of light. Watering can be done weekly during summertime, if the weather is sunny enough, with a little fertilizer added. Kept this way, plants will show a healthy, although slow growth.

Propagation: Usually by grafting or occasionally by cuttings in late spring to summer,  just take a cutting of the plant let it dry for 1 or 2 weeks and stuff it in the ground (preferably dry, loose, extremely well draining soil).
