Echinocereus parkeri

It is a cylindrical cactus with a columnar habit. The light green stem, which can branch at the base, has thin tuberculous ribs, equipped with round areoles. From these areoles whitish spines emerge: the radial ones are straight, arranged in a star shape; the central ones are longer, which tend to go upwards. During spring, it blooms with funnel-shaped flowers with narrow petals of an intense magenta color.
