Pachypodium brevicaule is a species of plant that belongs to the family Apocynaceae.
Agave attenuata, commonly called the foxtail or lion's tailagave or the swan's neck agave, is a species of flowering plant in the family Asparagaceae. Sometimes called the soft-leaf or soft-leaved agave, the aforementioned animal-related names are a nod to the appearance of the plant's inflorescence, which—after years, generally—rises slightly before gravity brings it back down, giving the bloom a curved, "swan"-like or "foxtail" look. The species' specific manner of flowering is unique in the genus Agave as most other species produce a towering, vertical display, reminiscent of a miniature tree.
Salvia columbariae is an annual plant that is commonly called chia, chia sage, golden chia, or desert chia, because its seeds are used in the same way as those of Salvia hispanica (chia). It grows in California, Nevada, Utah, Arizona, New Mexico, Sonora, and Baja California, and was an important food for Native Americans. Some native names include pashiiy from Tongva and it'epeš from Ventureño.
Agave deserti is an agave native to desert regions in southern California, Arizona, and Baja California. Its tall yellow flower stalks dot dry rocky slopes and washes throughout the spring.
Agave shawii is a species of monocarpic succulent plant in the genus Agave, commonly known as Shaw's agave. It is a rosette-forming plant characterized by glossy, green leaves with toothed margins. After several years of slow growth, the plant puts all of its resources to produce a towering stalk of flowers, and then dies. The death of the flowering rosette is compensated by the growth of numerous clonal pups. This species is segregated into two subspecies, one native to the coast of southwestern California and northwestern Baja California, known commonly as the coast agave, and another native to the Baja California desert, known as the Goldman agave.
Chorizanthe orcuttiana is a rare small annual plant in the buckwheat family, Polygonaceae. It is known commonly as Orcutt's spineflower or the San Diego spineflower, and it is endemic to San Diego County, California. The plant is diminutive, and a hand-lens is necessary for proper identification. The plant is very sensitive to temperature and precipitation, and under drought or hot conditions the seeds will not germinate or survive. The plant is visible anywhere from February through July during good rain year, but most years the plant is only visible from April to June. Each minute flower yields one seed.
Agave utahensis is a species of agave known by the common name Utah agave.
Dudleya pulverulenta is a species of perennial succulent plant known by the common names chalk lettuce, chalk dudleya, and chalk liveforever. It is one of the largest Dudleya, with a silvery, waxy rosette that may greatly contrast with its habitat. It is also regarded as one of the most distinctive members of the Dudleya, with one of the most specialized inflorescences in the genus, adapted to hummingbird pollination through its red pendent flowers, the longest corolla, and the highest nectar output. Dudleya pulverulenta has the largest range of all Dudleya, over 1,000 kilometres (620 mi), being found from southern Monterey County in California to the Sierra de San Borja in southern Baja California. It is closely related to Dudleya arizonica, a smaller desert species that tends to lack the specialized floral traits, and Dudleya anthonyi, which differs in a few morphological traits and is restricted to the San Quintín Volcanic Field.
Gilia cana is a species of flowering plant in the phlox family known by the common name showy gilia. It is native to California and Nevada where it grows in open areas with gravelly and sandy soils, such as desert and rocky slopes. The Mojave Desert range of some subspecies may extend into Arizona.
Agave salmiana is a species of the family Asparagaceae, native to central and southern Mexico. It is also reportedly naturalized in South Africa, Italy and Spain, specially in the Canary Islands.
Agave is a genus of monocots native to the arid regions of the Americas. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves.
Agave phillipsiana is a rare species of flowering plant in the asparagus family known by the common names Grand Canyon century plant and Phillips agave. It is endemic to Arizona in the United States, where it lives only in Grand Canyon National Park. It is a perennial herb or shrub.
Agave schottii, also known by the common name Schott's century plant, is a shrub species within the genus Agave. It is a member of the subgenus Littaea. There are two widely recognized varieties of this species: Agave schotti var. schottii and Agave schottii var. treleasei.
The agricultural practices of the Native Americans inhabiting the American Southwest, which includes the states of Arizona and New Mexico plus portions of surrounding states and neighboring Mexico, are influenced by the low levels of precipitation in the region. Irrigation and several techniques of water harvesting and conservation were essential for successful agriculture. To take advantage of limited water, the southwestern Native Americans utilized irrigation canals, terraces (trincheras), rock mulches, and floodplain cultivation. Success in agriculture enabled some Native Americans to live in communities which numbered in the thousands as compared to their former lives as hunter-gatherers in which their bands numbered only a few dozen.
Agave palmeri is an especially large member of the genus Agave, in the family Asparagaceae.
Agave delamateri is a species of plant in the agave subfamily, Agavoideae. It is known by the common names Tonto Basin agave and Rick's agave. It is endemic to central Arizona in the United States. It is generally found on gravelly soils in desert scrub and sometimes pinyon-juniper woodland, often near Mogollon or Salado archaeological sites.
Agave margaritae is a species of plant from the Agave genus. Its common name in English is "Magdalena Island Agave".
Agave gigantensis is a large, flowering agave plant found in Baja California Sur, Mexico. Its name is derived from the area of origin, not its large size. The plant is distinguishable by its red and purple leaves during flowering season. It is able to survive in harsh, rocky conditions and prefers dry and warm environments. The flowers of A. gigantensis are arranged in small clusters which diverge from a main branch. Unlike many other agave plants, A. gigantensis has been traditionally used in food and medicine by communities of western Mexico.
Dudleya arizonica is a species of perennial succulent plant commonly known as the Arizona chalk dudleya and the Arizona liveforever. A member of the genus Dudleya, this species is characterized by long, red flowers that adorn a waxy rosette of succulent leaves. It resembles a reduced desert form of the more coastal chalk dudleya, Dudleya pulverulenta, but differs in its smaller stature, lower number of leaves, and orientation of the flowers. Native to the southwestern United States and northwestern Mexico, it is widespread in range, but is primarily found in scattered, widely separated localities. It can be found as far west as coastal Ensenada to the desolate desert ranges of Nevada. It is one of two species of Dudleya that occur in Arizona, the other being Dudleya saxosa subsp. collomiae, and is the only species on mainland Mexico and in Utah.
Mucronea californica is a rare species of annual plant in the family Polygonaceae known by the common names California spineflower or California mucronea. An ephemeral plant found growing in the sandy microhabitats of coastal sage scrub, chaparral and dunes, this plant is threatened by the urbanization and development of its viable habitat and has been locally extirpated over much of its range. It has small, white to pink flowers that top inflorescences spined with awns.
