Description: The ssp. wrobelianus differs minimally from ssp. horripilus for its almost white radials and for the darker brow to black central spine (versus tan to brownish spines), and for the little smaller flower. It is a clustering species (rarely solitary) that branches profusely from the base and thereby forming large groups up to 30 cm in diameter.
Subspecies, varieties, forms and cultivars of plants belonging to the Turbinicarpus horripilus group
Turbinicarpus horripilus (Lem. ex Förster) V.John & Říha: Pungent pale to dark brown spines with blackish tip that become greyish white, areoles with white wool (when young), soon becoming bare.- Turbinicarpus horripilus subs. kvetae (Chvastek & Halda) Chvastek & Halda
- Turbinicarpus horripilus f. monstruosa: It forms dense clusters, composed of a great number of soft green stems, each of them usually less than 2 cm wide, some only a few mm across. The spines are all radials: 1-3 mm long, bristle-like, somewhat bent.
- Turbinicarpus horripilus subs. wrobelianus Nitzschke & Montes: has almost white radials and darker brow to black central spine (versus tan to brownish spines), and a little smaller flower. Distribution: North of Metztitlan near Jilos (Gilo, Xilo), Hidalgo, Mexico.
Cultivation and Propagation: It’s a fairly easy species to cultivate and relatively fast growing. Need a very well drained soil. Requires strong sun to part sun to develop good spinal growth and waterings should be rather infrequent to keep the plant compact and not to become excessively elongated and unnatural in appearance. Careful watering away from the body of the plant will allow the areoles to keep their wool. keep dry in winter or when night temperatures remain below 10° C, it is hardy to -4°C for a short period. Assure a good ventilation.
Reproduction: From seed, since the plant rarely produces plantlets, or grafted.
