58. Pencil cholla

Common along banks of washes and on desert flats, this cholla, also

called “tesajo,” or “Christmas cholla,” is so slender-stemmed and

sprawling in growth habit that it is easily overlooked in a tangle of

vegetation. Its flowers, appearing in May and June, are small and

inconspicuous, but the orange to scarlet fruits about the size and shape

of olives, are striking eye-catchers in the fall and winter months. In

the open the shrubby plants are rarely more than 2 feet high, but in

thickets of northern Mexico some have become almost vinelike, growing up

through mesquite or paloverde trees to a height of 12 feet or more. The

species grows at elevations of 200 to 5,000 feet from Texas to western

Arizona and northern Mexico.
