Saguaros and Palo Verde Tree Blooming

The saguaro (Carnegiea gigantea) is an arborescent (tree-like) cactus species in the monotypic genus Carnegiea, which grows to be over 40 feet (12 m) tall. It is native to the Sonoran Desert in Arizona, the Mexican State of Sonora, and the Whipple Mountains and Imperial County areas of California. The saguaro blossom is the state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie. In 1994, Saguaro National Park, near Tucson, Arizona, was designated to help protect this species and its habitat.

The image of the saguaro is indelibly linked with that of the American Southwest, especially in western films. The common name saguaro came into the English language through the Spanish language, originating in the Mayo language.
This plant is primarily found in the Sonoran Colorado Desert of southeastern California, and the Sonoran Deserts of southern Arizona and of northwestern Sonora state (Mexico). It is found predominantly in desert washes or bajadas, a result of its need for water, although occasionally it can be found in creosote desert scrub habitat, accessing seeps in desert hills up to 3,600 feet (1,100 m). Also found in the far eastern Mojave Desert of California in the northern Lower Colorado River Valley, and occasionally in the Mojave’s mountains.

The Palo Verde grows to heights of 10–12 metres (33–39 ft). It is a rapidly growing large shrub or small tree, and rarely survives to 100 years. Compared to the closely related Parkinsonia microphylla (foothill paloverde), is taller, and matures more quickly.

The plant’s trunk, branches, and leaves are blue-green in color, hence the common name. The plant is drought-deciduous, shedding its foliage for most of the year, leafing out after rainfall. Photosynthesis is performed by the blue-green branches and twigs, regardless of absent leaves.

The flowers are bright yellow, and pea-like, which cover the tree in late spring. They attract pollinators such as bees, beetles, and flies. They are followed by seed pods which are slightly larger and flatter and have harder shells than the foothill paloverde. These are a food source for small rodents and birds.
