Chisos Mountain Hedgehog Cactus Plant Information

Chisos Mountain Hedgehog Cactus grows in the following 1 states:


Echinocereus chisoensis is an inconspicuous plant, forming small loose clumps. Stems are up to 30 cm (1 foot) long, sometimes erect but sometimes partially reclining on the ground. Flowers can be up to 10 cm (4 inches) long, whitish along the throat, with red or purple spots near the base, and pink near the tips. Anthers are yellow, fruit green.Echinocereus chisoensis is a rare North American species of cactus known by the common name Chisos Mountain hedgehog cactus, native to the Chihuahuan Desert of northern Mexico and the south-central United States.

There are two varieties of this species, both rare.
The variety Echinocereus chisoensis var. fobeanus is known only from south of the Ro Grande, between Coahuila and Durango in Mexico. This variety is sometimes regarded as a distinct species, Echinocereus fobeanus.
The rare variety Echinocereus chisoensis var. chisoensis is known only from alluvial flats in desert scrub habitat. The soil is rocky and gravelly. It is endemic to Brewster County, Texas, with all occurrences located within Big Bend National Park. It is a federally listed threatened species of the United States. Other plants in the area include creosote (Larrea tridentata) and lechuguilla (Agave lechuguilla). Creosote and similar shrubs act as nurse plants for the cactus.
The "incredibly spectacular" pink flowers of this plant have made it a target for cactus collectors, who are a major threat to the survival of the species. There are only about 1000 individuals existing.
Because it is self-incompatible, flowers of one cactus require pollen from another individual of the species for fertilization; when plants are rare and spread apart, the likelihood that a pollinator will stop at the plant and deliver the correct pollen is lower. When fruits are successfully produced, they are often taken by jackrabbits and rodents for food. Dry conditions may increase this herbivory and decrease pollinator abundance.
