Echinocereus spp.

Echinocereus, also known as hedgehog cactus, is a genus comprising about 62 accepted species native to the southern United States and Mexico. This genus is characterized by low clumps of cylindrical or conical stems, sometimes containing a hundred or more plants, and spines are arranged along vertical ribs, and are always straight, never hooked. Echinocereus produce some of the largest and brightest blooms of any cactus. The flowers last slightly longer than those of other cacti and most species have edible fruit. They grow over a wide range of environments, from the low, hot deserts to cool mountain slopes, but most prefer unshaded conditions.
