Saguaro Cactus
Cereus giganteus or Carnegiea gigantea, Cactus Family ( Cactaceae ), Saguaro Cactus.

The saguaro cactus is a dominant form of the Sonoran Desert. A young saguaro takes nearly a decade to reach one inch tall, it can reach heights of about fifty feet, which makes it the largest cactus in the United States. The saguaro is a single-stemmed, columnar cactus supported by woody ribs. The skin of the cactus is light green and waxy. Spines are clustered down the length of the ridges. At seventy-five years old, the cactus begins to sprout arms that grow parallel to the body. As many as fifty arms have been found on older saguaros estimated to be 200 - 300 years old. A Saguaro cactus can weigh over nine tons.

Saguaro flowers are pollinated by nectar feeding bats, birds and insects.

While a single fruit of a saguaro can produce over 2000 jet - black seeds; only a few of the seeds that a saguaro produces in its lifetime, will germinate and grow to maturity.

While many animals, birds, and insects enjoy the fruit of the saguaro, there are many of these creatures which also make their homes in the Saguaro. The most widely known of the birds are the Gila Woodpecker, which creates many of the nest holes seen in mature saguaro stems. Each year the woodpecker creates a new nest hole, and the previous one is then occupied by insects, lizards or occasionally by the Elf Owl. The gilded flicker also produces nest holes in saguaros. Occasionally, the major branches of saguaros can have large twig-nests of hawks such as the red-tailed hawk or the Harris hawk. At Alamo Lake there are Bald Eagles which nest on the top branches of the Saguaro.

Saguaro are located all over the state of Arizona mainly in the Sonora Desert. While there are three National Parks dedicated to the protection of the Saguaro, there are many other locations in Arizona with far better displays of Saguaros than what are in the National Parks.

While most Saguaro cacti grow in the typical fashion, a few individuals will grow in an atypical form known as a cristate or crested saguaro. These bizarre looking forms often grow as a crest

Height: Up To About 15' - 50' Tall.
Flowers: Creamy-white, About 3-inch-wide flowers with yellow centers bloom during May and June. Clustered near the ends of branches, the blossoms open during cooler desert evenings and close again by the next midday.
Blooming Time: May - June
Stem: From 1' - 3' in diameter consisting of an interior framework of about 12 - 30 or more woody ribs supports the spongy tissue. The waxy, fluted surface allows the cactus to expand like an accordion during the rainy seasons and shrink back down during the dry. The shallow roots spread out to over 40' and can absorb up to 200 gallons of water a week during the rainy season. In about one out of 200,000 saguaros, the top mutates to form a crest called a cristate.
Fruit: The fruit is up to 1 3/4"X3" with an egg shape, the green fruit ripens over about a 45 day period of time and turns a dark red color then just before the fall rainy season, it splits open to reveal bright-red, pulpy flesh which many of the desert creatures seem to enjoy. This fruit was a food source to the Native Americans of Arizona who used the flesh, seeds and juice.
Leaves: Cactus thorns are modified leaves. Their shape conserves water and adds protection to the cactus plant.
Found: Lower Elevations of the Sonoran Desert of Arizona and California. Also Sonora, Mexico.
Elevation: 0 - 3500 Feet.
Habitat: Desert slopes and flats, rocky bajadas. The saguaro begins life under a "nurse" plant, typically a palo-verde or mesquite tree. The tree provides shade and increased water availability during the summer, and protects it from winter frosts.
