Echinocereus is a genus of ribbed, usually small to medium-sized cylindrical cacti, comprising about 50 species from the southern United States and Mexico. They are commonly known as hedgehog cacti, although that name is also used for Pediocactus and Echinopsis species. The flowers are usually large, and the fruit are edible. Most Echinocereus species prefer full sun. Several of the species are cold-hardy, tolerating temperatures as low as -23°C / -10°F in dry conditions.
