Mammillaria bocasana is a species of cactus in the subfamily Cactoideae. It is often sold as a "powder puff" cactus,[1] and also as a "Powder Puff Pincushion."[2] The plant is protected from collecting in the wild in Mexico.[3]
Habitat
In its natural habitat of Northern central Mexico, it is found between 1650–2300 meters above sea level.[2] It grows on canyon walls, in volcanic rock and in semi-desert environs, often under bushes of native plants.[2] It has been listed as "Least Concern" on the IUCN Red List of Threatened Species since 2009.[3]
Description
Mammillaria bocasana is hemispherical in shape. It has "white, hair-like spines" that cover up its radial and hooked central spines.[1] 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.[2]
Cultivation
Mammillaria bocasana can be propagated from seed.[1] 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.[1] It has gained the Royal Horticultural Society's Award of Garden Merit.
