Mammillaria luethyi is a tiny, ball-shaped cactus from the Chihuahuan Desert in Coahuila, Mexico, known for its white spines and magenta flowers. It is grown as a specimen cactus and is rare in the wild, so it should be kept in bright light and a very well-drained mineral mix.
Mammillaria luethyi is a species of cactus endemic to the Mexican state of Coahuila. The plants are miniature, shaped like balls and covered with tiny white spines and, throughout the summer, large magenta flowers.
The species entered scientific discourse in 1952, when Oklahoma professor Norman Boke found the hitherto undescribed cactus blooming on Mrs Crosby's windowsill. The plants were sent to Ladislaus Cutak of the Missouri Botanical Garden for research, but died soon after arrival. For 44 years the species was known solely from a couple of photographs and Cutak's description, captivating cactus experts.
Because the publication of Geohintonia mexicana earlier in the 1990s was followed by illegal collection of the plants, Hinton published his 1996 description of Mammillaria luethyi in Phytologia, a botanical journal, rather than in a specialized cactus journal. The rediscovery of the species thus went unnoticed by cactus enthusiasts until 1998, when it was publicized in the Cactus and Succulent Journal.
Eight Mammillaria luethyi plants were collected during the initial type collection in 1996. These plants were propagated at the Cante Botanical Gardens in San Miguel de Allende under the supervision of Charlie Glass. From here the species was distributed to Mexican growers. A harsh winter in 1997/1998 caused significant frost damage to the botanical garden's collections, prompting an urgent need for funding. Around this time, two cactus enthusiasts from the Czech Republic and Slovakia offered a $2,000 donation in exchange for two M. luethyi specimens. The plants arrived in Prague in June 1998. Within a few years, M.
Mammillaria luethyi is found in the Chihuahuan Desert in the north of the Mexican state of Coahuila, at elevations of around 800 m. These plants thrive on horizontal slabs of limestone, nestled deeply within an extremely shallow substrate just 1.5–2.0 cm thick, composed of sandy clay and fine gravel, with which the tiny plants blend. They grow alongside Selaginella wrightii, Neolloydia conoidea, Bouteloua gracilis, and various lichens. Surrounding their microhabitats is the characteristic vegetation of the Chihuahuan Desert, dominated by species such as Agave lechuguilla, Dasylirion, Escobaria tuberculosa, Fouquieria splendens, Glandulicactus uncinatus, and Yucca species including Y. elata.
