Calochortus nuttalii aureus Lily Family

7. Desert mariposa

Brightest of the mariposas, the short-stemmed, flame-like flowers usually appear singly, but may occur in patches, producing in April a spectacular display visible from a long distance. Plants growing under bushes elongate their stems to elevate their blossoms into the sunlight. Occasional in the Mojave-Colorado Desert, this species is abundant in the foothills of some of southern Arizona’s mountain ranges, exceeding even the goldpoppy in the neon-like brilliance of display. Mariposa is Spanish for butterfly, and the genus name calochortus is Greek for beautiful grass.

8. Soaptree yucca

Common throughout the Southwest, the many species of yuccas (YUH-kuhs) are of two major groups, the narrow-leaf and the wide-leaf. Called “soaptree” because of its height (maximum 30 feet) and the fact that its roots contain saponin, soaptree yucca or palmilla (pahm-EE-yah—“little palm”) belongs in the narrow-leaf group. From southwestern Arizona across southern New Mexico, and from west Texas southward into the Mexican states of Chihuahua and Sonora, this spectacular plant blossoms in May and June on desert grasslands from 2,000 to 6,000 foot elevations. Cattle eat the young flower stalks, and Indians used the leaf fibers for making fabrics, basketry, and other items. The yucca is the State flower of New Mexico.

9. Joshua-tree

Another of the narrow-leaf yuccas and largest of the genus, the joshua-tree is restricted in its range to the Mojave-Colorado Desert, of which it is the principal indicator. Blossoms, which do not open as wide as those of other species, grow in tight clusters at the tips of the branches, appearing in March and April. Joshuas do not blossom every year, the interval between flowerings depending upon rainfall and temperature. A small night lizard is dependent upon the joshua-tree, at least 25 {species of birds find nesting sites in it, and numerous insects, spiders, and scorpions live in its dried leaves and fallen branches.}

10. Torrey yucca

Unlike the narrow-leaf soaptrees which produce dry, capsular fruits, the wide-leaf yuccas bear fleshy fruits which Indians cooked and ate. Indians also used the leaf fibers in weaving fabrics. Roots contain saponin and the Indians still cut them up and use the pieces for soap, especially as a shampoo. The stiff, fleshy leaves with needle-sharp tips give the plant the name “Spanish bayonet.” Torrey yucca blooms in April in southeastern New Mexico and west Texas, with similar plants, Yucca schottii in southern Arizona, and Yucca schidigera in the Mojave-Colorado Desert.

11. Giant yucca

Massive and thick-stemmed, the locally-named “giant dagger” is supposedly limited in its native range in the United States to Brewster County, Texas. A colony (Yucca faxoniana) resembling this species has been reported recently in McKittrick Canyon in the Guadalupe Mountains. An extensive forest of these spectacular plants has given the name Dagger Flat to a broad valley in the Sierra del Carmen of Big Bend National Park. Usually blossoming in April, the massive, white flower clusters gracing the crowns of thousands of these majestic yuccas create a never-to-be-forgotten spectacle. A small night-flying moth is the yuccas’ pollenizing agent and, in return for this essential service, lays her eggs in the plants’ ovaries where the young feed on the developing seeds.

12. Sacahuista

Sometimes confused with the yuccas, the several species of “beargrass” or “basketgrass” have pliant, grasslike leaves, small flowers, and papery fruits. The plumelike blossom panicles open in May and June. The plants favor rocky hillsides, and rarely occur on valley floors. Indians roasted the tender bud stalks for food, and cattle browse the leaves when other vegetation is lacking. Mexicans, in weaving basketry, use the entire leaves, which are especially desirable for fashioning basket handles.

13. Sotol

Also likely to be confused with the yuccas, sotol has a basal cluster of pliant, ribbonlike leaves edged with hooked thorns, and a tall flower stalk bearing at its upper end a dense panicle of small, creamy (sometimes brown) flowers. Blossoming in May and June, the maturing flower clusters remain attractive throughout the summer. Mexicans split the succulent basal crowns and allow the sap to ferment, producing the fiery alcoholic beverage, sotol (SOH-tole). Desert-dwelling bighorn sheep are said to browse the tough leaves. The stiff leaf bases, when pulled from the cluster, form the “desert spoons” sold in some curio stores.

14. Agave

Many species of agaves (ah-GAH-vees) or “century plants” attract attention on desert hillsides when they send up their tall blossom stalks in June and July. The thick, fleshy, sharp-tipped leaves form a basal rosette. Some of the larger species may require 10 to 20 years to store enough plant food to produce the sturdy, fast-growing flower stalk. After blossoming, the exhausted plant dies. Agave scabra, one of the spectacular forms, is limited in its range to the Chisos Mountains of Big Bend National Park, Texas.

15. Parry agave

Another of the large “century plants,” Parry agave blooms from June to August, producing spectacular displays on hillsides in northern Mexico, southern New Mexico, and southern Arizona. Some of the larger agaves are called mescal (mess-KAHL) because of a potent alcoholic beverage of that name distilled from the fermented sap derived from the bud stalks. Tequila (tee-KEEL-ah), the famous native drink of Mexico, also is distilled from fermented agave juices, and the beerlike pulque (pool-KAY) has a similar derivation. Indians roasted the bud stalks in stone-lined pits covered with hot rocks. Some of these pits may still be seen.
