"Arizona Snowcap" shows an odd thickening and shortening of the spines, resulting in a most attractive, unusual looking plants.
Today this cultivar is very common, but rarely it is cultivated in the appropriate way (full sun). But the specimens correctly cultivated are really admirable.
In the photo is shown a compact plant densely covered by candid spines . A true beauty!!!
Cultivation: Readily forms many offsets from sides and top. It does best in a mineral soil, good drainage is essential. Water sparingly during the summer months and keep dry in winter. It is a slow growing plant and once established, it will be content in its position and with its soil for years. Extremely hardy, can tolerate full sun, long periods of dryness and light frost (-4° C). It can also grows in moderate shade, and a plant that has been growing in shade should be slowly hardened off before placing it in full sun as the plant will be severely scorched if moved too suddenly from shade into sun.
Propagation: It is propagated exclusively from cutting during spring or summer.
