Where it grows
This cactus is indigenous to Mexico.
Special features
This is the rare monstrose form of Mammillaria longimamma. Instead of the normal finger-like protrusions from its stem, these specimens exhibit a compact, pineapple-like stem form.
Care Guide
Like most Mammillaria, this is a desert species and prefers full morning sun during the growing season of summer. It needs a gritty soil mix with very little organic components to mimic the soil in its natural habitat. Water it well during spring and summer, but keep it totally dry in winter.
Growing season
Spring and summer.
Propagation
Seeds and offsets.
