Plant Bio
Mammillaria hahniana · the “Old Lady Cactus”
This pincushion cactus is a form of Mammillaria hahniana, native to the dry, rocky highlands of central Mexico, including the state of Hidalgo. Mammillaria is one of the largest cactus genera, and this is one of its most beloved members.
It forms a tidy green globe almost completely veiled in fine white spines and long white hairs — the soft, silvery look that earns the species its nickname, the “Old Lady Cactus.” Underneath, the body is patterned in neat spiraling rows of tubercles.
In spring, mature plants crown themselves with a ring of small magenta-pink flowers around the top — a classic Mammillaria display. With age it clusters into a cushion of several heads.
It’s an easy, rewarding cactus: give it strong light, gritty soil, careful watering, and a cool dry winter, and it will reward you with that flower ring.
How is it different from other small cacti?
- It’s wrapped in fine white hairs as well as spines, giving a soft, silvery look.
- It flowers in a distinctive ring around the crown, typical of Mammillaria.
- It clusters with age into a cushion of heads rather than staying a single ball.
Note: The fine spines can irritate skin, and the plant may cause discomfort if ingested. Handle with care and keep out of reach of pets and children. Grown for ornamental purposes and not intended for consumption.
