Mammillaria gracilis cv. Arizona Snowcap
Accepted Scientific name: Mammillaria vetula ssp gracilis
Description: Mammillaria "Arizona Snowcap" is a monstrous form of M. vetula ssp. gracilis which is characterised by densely packed separate clusters of spines. It looks so different to the wild species that it isn’t easy to realise that they are related. This cultivar offsets generously from sides and upper part of plant, which gives it a snowball appearance. Mature group can reach 10-12 cm in diameter and 6-8 (10) cm in height.

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.
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.
