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.

Fertilize sparingly with specialized cactus fertilizer
- always use gloves when handling a cactus
- for repotting fold up a few sheets of newspaper into a thick flat band. Surround the cactus with this band handle him
- remove the spines from the skin by applying a patch of adhesive tape and removing it
- use a mix of topsoil, sand and gravel (1:1:1) and sterilize that (eg in the microwave)
- fill a pot with it and wet the substrate by placing it 2 hours in a bowl with water so the water is sucked up
- sow the seeds on the surface and press very lightly
- place the pot with seeds in a plastic bag and close it
- place the pot in a bright location out of direct sunlight
- 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
