Recognized subspecies, varieties and forms:

  • subsp. taltalensis: This taxon is characterized by straight spines and red, pink, cream or whitish blooms and comprises two variety: var. taltalensis with red or cream flowers and var. pygmaea with white or pink flowers.

  • subsp. echinus: Is has usually bi coloured flowers white below fuchsia or red above and comprises two variety: var. echinus with stems having short apical wool and var. floccosa with apexes covered by long wool.

  • subsp. paucicostata: It is the larger form with often elongated stems, the flowers are yellow to red.

  • subsp. pilispina: Has thin twisted spines and white flowers.

Cultivation:  It is a summer-growing species of relatively easy cultivation. It has a thick taproot and is susceptible to over-watering if kept in a non ventilated place. , sometimes it is  grafted to avoid root rot problems. Likes warmth (recommended minimum winter temperature 5° C) But plant kept perfectly dry can easily survive to winter night temperatures below 0° C. Sun Exposure: Suited for sunny-brightly exposure; can tolerate light shade.
Cultural Practices:
Suited for airy exposures.
Needs deep pot and gritty mineral substrate with a very good drainage to accommodate its tap root. Water regularly in summer, keep dry in winter.

Propagation: Usually propagated from Seeds. (seldom produces offsets) or graft. Seeds can be sown in the spring or summer. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots.
