Pincushion Cactus

Cochemiea fraileana

Cochemiea fraileana (Britton & Rose) P.B.Breslin & Majure in Taxon 70(2): 319. (2021)

Some facts about this taxon, one of several species in tribus Cacteae to be called "Pincushion Cactus":

  • Size of stem: 3–4 cm in diameter, 15 cm tall.
  • Size of flower: 2.5–3 cm in diameter.
  • Color of flower: Light pink; petals with darker pink median line, stigma yellowish-green.
  • Blooming season: May to September.
  • Habitat: Grows in non calcareous rocks.
  • Place of origin: The small islands of Pichilinque, Cerraibo and Santa Catalina off Baja California.
  • First described: By Nathaniel Lord Britton and Joseph Nelson Rose in 1923 as Neomammillaria fraileana. In 2021, Peter B. Breslin and Lucas C. Majure assigned it to the genus Cochemiea. There are at least six synonyms to the currently accepted taxon name, including a couple which at the time were ranked as subspecies of Cochemiea albicans.

Cochemiea fraileana is pricky but beautiful, with bell-shaped pink flowers. The elongated, club-shaped fruit is pinkish-lilac or red, and the seeds are black. Studies have shown that this species is a pioneer cactus in rock-colonizing. It belongs to the largest of several genera of diminutive cacti with about 175 species worldwide.

This plant is not very widely cultivated, because it needs a certain amount of heat in the winter, and a moist atmosphere while rooted in a fairly dry substrate. Propagation can be achieved either by vegetative reproduction via cuttings, or sexually by seeds: note however that the plant needs maximum sunlight to grow and achieve success in flowering. Letting the plant rest in winter to shrivel, even losing up to 25% of its summer height, will help the flowering process.
