Scientific name: Mammillaria
huitzilopochtli D.R. Hunt
Published in: Cact. Succ. J. (GB) 41(4): 106 (1979)
Origin: Mexico (Oaxaca, Puebla). Altitude 500 - 2.600 m.
Habitat and ecology: It
is an obbligate
saxicole that grows on vertical cliffs. Due to their verticality,
cliffs avoid sunlight at noon, providing a cool refuge during the
hottest hours of the day. Living on the cliff may be costly because
radiation is reduced but on steeper slopes plants find refreshment when
the climate is hot. This may contribute to explain why cliff-dwellers
have evolved in so many succulent-plant families.
Conservation status: Listed in
CITES appendix 2.
This is a beautiful plant with short starry clusters of spines.
Cultivation: It is a
relatively rapid growing species.
This is easily grown into clumps, but it does often have
an irregular pattern of offsetting. Water regularly in summer, but
do not overwater (Rot prone) Use pot with good drainage and a very porous
potting media, keep dry in winter.
Feed with a high
potassium fertilizer in summer.
It is quite frost resistant if kept dry, hardy as low as -5° C.
Outside full sun or afternoon shade, inside needs bright light, and some
direct sun. Easily flowering. Most
plants will offset readily, and clumps can be produced in a few years.
Propagation: Division, direct sow after last
