Lemaireocereus thurberi Cactus Family
ORGANPIPE CACTUS
[49.] Claretcup echinocereus
Not only are there many species of Echinocereus, popularly called the “hedgehog cactuses,” but there are also several varieties of Echinocereus triglochidiatus. One variety sometimes develops into cushion-like mounds composed of several hundred oblong stems huddled together with a seemingly precarious foothold in crevices among the rocks or on rocky slopes of the Mojave desert. Another grows in loose clusters of cylindrical stems in the higher desert grasslands up to the oak belt in the mountains of southern New Mexico, Arizona, and northern Mexico. When blossoming in May and June these clustering “hedgehogs” create a spectacular display.

CLARETCUP ECHINOCEREUS
[50.] Strawberry echinocereus
One of the more common species of “hedgehog,” sometimes called “Engelmann echinocereus,” the strawberry echinocereus grows as 2 to 12 or more robust, cylindrical stems up to a foot in height, among the creosote bushes and bur-sages of the Sonoran and Mojave-Colorado Deserts, flowering from February to May. Flowers close at night and reopen the following morning. Blossoms vary considerably in color from purple to lavender. Spines, too, are variable, from gray and yellow to dark brown. In southeastern California, where it is common, this species is called “calico cactus” because of its many-colored spines. Fruits of some varieties (of which there are many) are edible, forming an important item in the diet of birds and rodents.
