Part 12

Also called “tickseed,” wild coreopsis is closely related to cultivated ornamentals of the same name. The desert species inhabits open locations at elevations between 1,500 and 2,500 feet in southern Arizona, southern California, and Baja California. Plants usually bloom between February and May. The closely related Coreopsis bigelovii is a southern California annual having somewhat larger flowers, up to 2 inches in diameter, with orange centers. Flower stems are naked, with the leaves clustered at their bases.

91. Paperflower

At its best in sandy desert soil, paperflower is a compact, shrubby plant about 1 foot high, with tangled branches. When fully developed it is symmetrically globular in outline. It prefers mesas and desert plains at elevations between 2,000 and 5,000 feet from western New Mexico to southern California and northern Mexico, flowering throughout the year but most abundantly in springtime. Sometimes called “paper-daisy,” the flowers are persistent, fading to straw color and turning papery with age. They may remain on the stems for weeks.

92. Desert baileya

Commonly called “desert marigold,” baileya blossoms in all seasons, most heavily from March to November, and is one of the better known flowers of the Southwest. Each circular blossom occupies the tip of a foot-high stem. Plants usually have a thrifty, garden-variety appearance. They are common along roadsides and on well-drained, gravelly slopes up to 5,000 feet from west Texas to southeastern California and Chihuahua. The large flower heads are showy and the species is cultivated in California. Cases are on record of sheep and goats on overgrazed ranges being poisoned by eating this plant.

93. Goldfields

Covering vast stretches of open desert with a carpet of yellow bloom following wet winters, goldfields is an appropriately named spring flower found at elevations below 4,500 feet. The low-growing plant produces small but attractive blossoms on mesas and plains, March to May, from central and southern Arizona to California, and Baja California. Horses graze Baeria avidly, but are annoyed by a small fly that frequents the fragrant blossoms, giving the plant the name “fly flower” in some localities.

94. Chaenactis

Probably because it is one of the attractive white desert flowers, chaenactis is popularly called “morning bride.” A larger, yellow-flowered species, Chaenactis lanosa, found on the California deserts, is called “golden girls.” Both are spring flowering annuals and, in common with other members of the genus, sometimes called “pincushion plants.” “Morning bride” is often found growing about the bases of creosotebushes, thriving at elevations between 1,000 and 3,500 feet in southern Nevada, western Arizona, and southeastern California.

95. Douglas groundsel

Rarely considered beautiful, the groundsels are common and widespread, and are readily recognized by the untidy appearance of the large flowers which are sometimes almost 2 inches in diameter. The rather delicate, stringy foliage is sometimes covered with cottony threads. One species is called “ragwort.” Douglas groundsel is a shrubby plant sometimes as much as 3 feet high, common in sandy washes and on dry foothill slopes. It occurs from southern Utah and Arizona to California and Mexico, between 1,000 and 6,000 feet. At lower elevations these plants bloom at almost any time of year.

96. New Mexico thistle

Everyone recognizes the thistles with their prickly leaves and stems, and large flowers ranging in color from white to lavender, pink and purple. Several species grow in the deserts, the New Mexico species being widespread at elevations from 1,000 to 6,000 feet in Colorado and Nevada south through New Mexico and Arizona to California, blossoming from March to September. Navajo and Hopi Indians are reported to use thistles medicinally. The nectar of some species is eagerly sought by hummingbirds.

97. Desert dandelion

A very attractive plant, desert dandelion has several flower stalks from a few inches to a foot tall. Some of the blossoms may be nearly 2 inches in diameter. This annual is common in open, sandy basins, where it is a conspicuous contributor to the spring flower spread, blooming from March through May in the creosotebush belt of Arizona and southern California. It has been reported from as far north as Idaho and Oregon. Sometimes a single plant has 10 or 12 flower heads in blossom at the same time.

98. Malacothryx

There are many species of malacothryx native to the western and southwestern United States. Some are locally called “desert dandelion,” “snake’s head,” “yellow saucers,” and “cliff aster.” Fendleri is one of the smaller species, with stems only 4 or 5 inches long, rising from a rosette of bluish-green leaves. Blooming from March to June, this delicate relative of the common dandelion covers with its pale yellow flowers rocky slopes and sandy plains and mesas, at elevations between 2,000 and 5,000 feet from West Texas to western Arizona.

99. White cupfruit

Also called “tackstem” because of the numerous dark-colored, tack-shaped glands protruding from the stem, this white-flowered, branching annual blossoms from March to May at elevations of 500 to 4,000 feet. It is a conspicuous item of the spring flower display from west Texas to southern California and northern Mexico. A similar species with yellow flowers, Calycoseris parryi, common at elevations around 3,000 feet, blooms in March and April. It is found in southwestern Utah, Arizona, and southern California.
