Mammillaria hahniana is part of the Cactaceae family and its native range is NE. Mexico (to Jalisco). It grows on relatively steep slopes in submontane matorral and deciduous forests. It is easily identified by its long, white, thin, flexible hairs which can densely cloak the plant's body and increase in thickness, richness and length in age. This cactus is known for its flowers, which form in concentric rings of small violet-red to pink blooms, a(12-15mm in diameter) .
Genus name comes from the Latin mammilla, meaning ‘nipple’ or ‘teat’ this is in reference to the tubercles that are a distinctive feature of the genus.
Pot: ø 8.5cm
Height: Approximately 13cm from base of pot.
Light: Allow the plant to see the sun for as many hours of the day as possible; the plant ought to be able to see sun from where it is positioned in the home. A south facing window is ideal.
Water: Allow the potting mix to dry out completely in between waterings; Mammillaria hahniana prefer to stay on the dry side. During the winter water very infrequently, if at all, this will encourage flowering during the spring!
Potting mix: A well draining mix composed of perlite, grit and horticultural sand and a small amount of coco coir.
Fertilising: Feed every few waterings during the growing season. You can dilute fertiliser to half the recommended amount but never add more.
Temperature: Temperatures over 21˚C.
Humidity: Low humidity; if the humidity is particularly high, good ventilation is key to prevent mildew and fungal disease.
Mammillaria hahniana are non-toxic, but spiky so keep out of reach of pets and children.
