Habitat

In its natural habitat of Northern central Mexico, it is found between 1650–2300 meters above sea level.[3] It grows on canyon walls, in volcanic rock and in semi-desert environs, often under bushes of native plants.[3] It has been listed as "Least Concern" on the IUCN Red List of Threatened Species since 2009.[1]

Description

Mammillaria bocasana is hemispherical in shape. It has "white, hair-like spines" that cover up its radial and hooked central spines.[2] During the spring and summer, it bears several cream-colored flowers.[4] Later it bears a red cylindrical fruit that contains reddish-brown seeds which display partially lateral hilum.[5] Its form can be variable, with many different varieties or subspecies.[3]

Cultivation

Mammillaria bocasana can be propagated from seed.[2] As it grows, it offsets, creating large mounds.[4] This cactus is prone to rot and can tolerate temperatures of -7 degrees Celsius (20 degrees Fahrenheit) for short amounts of time.[2] It has gained the Royal Horticultural Society's Award of Garden Merit.[6]
