Mammillaria spinosissima "rubrispina"
(syn: M. spinosissima cv. "Super Red")

CACTUSPEDIA       

 


Mammillaria spinosissima "rubrispina"
Red spine selection.
 

Description: Columnar plants, usually solitary but they can form pups on old plants. M. spinosissima is very variable due to its wide area of origin in Mexico. The color of the spines vary from red or rust to white. The “rubrispina” selection forms nice clumps of columns, densely spined with bright coppery red spines.
Stem: Cylindrical, dark blue-green, rarely exceeding 30 cm in height, 6 - 7 (10 cm) cm in diameter. Without latex. Parastichy: 13 - 21
Tubercles: Ovate conical, four-sided basally. The axil is slightly woolly.
Radial spines: 20 - 25, white, bristle-like, 4 - 6 mm long.
Central spines: 12 - 15, copper-red, stronger than the radials and thicker at the base, straight, 10 - 12 mm long.
Flowers: Vivid purple/ red to deep pink, 12 mm long and in diameter, encircling the columnar stems.
Blooming season: Late winter and spring,
Fruits: Purplish red or greenish.
Seed: Brown.

Remarks
: The Mammillaria spinosissima “rubrispina” also known as the "Red-headed Irishman" has very attractive copper/red coloured spines and is one of the most beautiful Mammillarias.

Recognized subspecies, varieties and forms:

  • The subspecies 'spinosissima' only rarely grows higher than 30cm. It has dirty white to coppery red spines and does not have bristles in the axils most of the time.

  • The subspecies 'tepoxlana' has yellow spines.
  • The subspecies 'pilcayensis' has whiter spines, and the stems can grow up to 50cm long/high. It might have some latex/bristles in the axils. The flowers are purple-pink on all subspecies

Cultivation: Its qualities and ease of cultivation justify that it is an old favorite.  It doesn't requires any special treatment, but needs as much light as possible (without burning the plant) to encourage the heaviest spine formation. Regular water in summer, dry in winter. Frost tolerance: -4° C.

Propagation: Seeds or offsets.
