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.
