Echinocereus triglochidiatus

Echinocereus triglochidiatus or Hedgehog Cactus is a cactus from southern North America and Mexico.

It is a small, compact shrub from a few to hundreds of stems. They form a cushion-like and hemispherical mound that gives the plant the appearance of a hedgehog.


The stem is cylindrical, up to 30 cm long and 2-6.5 cm thick, with 9-10 ribs.

The central spines are straight or slightly curved, the radial spines are smaller and at an acute angle to the central spines.

The flowers are bright red or orange-red, 2.5-5 cm long and appear just below the top of the stem. The flowers last 3-5 days. They are fertilized by sunbirds. The flowering takes place in April-June and the flowers remain open at night. It is the first cactus to bloom in spring.

The fruits are red and edible after the thorns have been burned.

  • place the pot with seeds in a plastic bag and close it
  • place the pot in a bright location out of direct sunlight
  • 25°C
  • regularly check that no fungi develop
  • when the seeds begin to germinate make a few holes in the plastic bag and then every week 2-4 additional holes for the seedlings to get used gradually to drier air
  • germination: 5-180 days
