One of the species that characterizes the Sonoran Desert is the saguaro cactus (Carnegiea gigantea). These plants are huge, tree-like columnar cacti, some of which never sprout arms or branches as they age. There may be over 25 of these arms, which often curve upward. Protective spines cover saguaros, which also have white blooms in the late spring and red fruit in the summer.
Habitat
Only the Sonoran Desert is home to saguaros. Temperature and water are the two main elements that affect growth. The saguaro can be killed by frost and cold weather if the height is too high. Although both winter and summer rains occur in the Sonoran Desert, it is believed that the Saguaro receives the majority of its moisture during the summer rainy season.
Range
This cactus can be found in western Sonora, Mexico, and southern Arizona. They are more common on the warmer south-facing hills in the northern part of their range. Southeast California is also home to a few stray flora.
Size
Cactus called saguaro grow very slowly. A plant that is 10 years old might only be 1.5 inches tall. Saguaro trees can reach heights of 40 to 60 feet (12-18m). When the saguaro is well-hydrated and there is plenty of rain, it can weigh between 3200 and 4800 pounds.
Quick Facts
The majority of the saguaro plant’s roots are merely 4-6 inches deep and extend outward as far as its height from the plant. One deep root, or tap root, penetrates the ground more than two feet deep.
When a saguaro dies, its woody ribs can be utilized to make furniture, fences, and roofs. Among the dead saguaros are the “saguaro boots,” or holes where birds formerly built their nests. Before the canteen was invented, Native Americans used these as water bottles.
What makes the saguaro cactus unique?
1. Saguaros can reach heights of more than 40 feet, making them the largest cactus species in the United States. (The huge cardon cactus, which is found in some regions of Mexico, is the largest species in North America.)
2. The average saguaro can live for 100 to 200 years. (However, according to Kevin Hultine, a plant physiologist at Phoenix’s Desert Botanical Garden, “We are not fully convinced of the true age of some of the largest individuals.”)
What is the purpose of the saguaro cactus?
The Hohokam people of the Tucson region employed saguaros in their daily lives, according to archeological data. The structure for the walls of their homes was built out of the sturdy, wooden ribs.
In addition, saguaro ribs were employed to harvest the plant’s high-growing saguaro fruits. A cross-shaped component was attached at the end to connect the various ribs. Ripe fruit was lowered from the top of the plants using these long poles. After that, people would assemble to eat. It is thought that the Tohono O’odham of today are Hohokam ancestors. The saguaro is revered as a holy plant in O’odham culture and should always be treated with care. The calendar is based on the cycles of the saguaro and features saguaro-related rites, such as one that involves fermenting saguaro fruit into wine.
As their forefathers did, the modern Tohono O’odham now pick saguaro fruit. They prepare the ceremonial wine from the sweet fruits, as well as jelly and candy. The saguaro seeds, which are strong in protein, are also used as poultry feed.
What distinguishes a saguaro from a cactus?
Fortunately, there are numerous, relatively simple methods for distinguishing between a saguaro and a barrel cactus. Let’s go over each one.
Size and Shape
The size and height of a saguaro cactus vs a barrel cactus are the most noticeable differences. Saguaros can reach a height of 50 feet, but it can take them 200 years to do so. The maximum height of a barrel cactus is only five to ten feet. Therefore, if the cactus you are observing is tree height, it is most likely a saguaro.
Of course, certain cacti species, like the prickly pear, can reach heights greater than your hip. However, they are not as spherical or swollen as barrel or saguaro cactus.
It should be rather simple to identify the species of cactus you’re looking at, even from equal heights.
A barrel cactus will never have branches, although a saguaro usually has a few. They won’t have any branches, although they might grow in bunches like rounded cactus.
Lastly, a saguaro will be narrower than it is tall. In relation to their height, barrel cacti are incredibly sturdy and thick. Remember that juvenile saguaro will be more angular than round, so keep that in mind!
Location
In North America’s Sonoran Desert, which stretches from northwest Mexico to the western part of Arizona, saguaro cactus are found (and a bit of California or Baja California). Outside of this region, it’s most likely not a saguaro.
Meanwhile, the saguaro’s range is largely occupied by barrel cacti in the southwest of the United States.
Fruits
Both barrel and saguaro cacti produce edible fruits. Saguaro fruits are around four inches long and emerge from the top of the shrub. They are oval in shape, crimson, and have spines.
Depending on the species, barrel cactus fruit can vary, although they are often yellowish or greenish. They are only two inches across and have a strong bitter flavor.
Flowers
Beautiful and white, saguaro flowers are stunning. It makes sense that it is Arizona’s official flower. The top of the plant and the tips of the branches are where the flowers develop. While a barrel cactus typically has orange, yellow, or pink flowers. When the plant is extremely old, they begin to grow in a circle around the top of the plant.
Root Systems
Although you might not be able to see the cactus’ root systems, there would be a noticeable change if you did. Deep roots help saguaro cacti maintain their height. A barrel cactus’ weak roots extend outward from the plant’s base.
Saguaro and barrel cacti both have a lifespan of more than 100 years. They contribute to the ecosystem by feeding animals and providing nesting space for some birds. You’ll discover that spotting the differences between these cactus species is easy with a little observation and practice!
What gives them the name “saguaro cactus”?
- Andrew Carnegie, a philanthropist, is honored with the name of the saguaro cactus (Carnegiea gigantea).
- Only in the Sonoran Desert can you find the saguaro cactus.
- Saguaro cacti develop very slowly. An adult saguaro can grow to a height of 60 feet, yet a juvenile cactus may only grow 1 to 1.5 inches in its first eight years. Their growth is influenced by the water supply.
- High-elevation saguaros typically cluster on warm, south-facing hillsides. Saguaro cacti cannot withstand freezing temperatures or frost, thus they are rarely found above 4,000 feet.
- The pleats on saguaros enable them to expand as they consume water (like an accordion) and to contract when they run out of water. The number of pleats on the saguaro’s exterior matches the number of woody ribs inside the plant.
- When saguaros are completely hydrated, they become incredibly heavy. Saguaros that are adults can weigh up to 4 tons.
- A saguaro begins to bloom around the age of 35 and develops its first arm around the age of 50. A saguaro is typically regarded as an adult at 125 years old. The saguaro has a 150–200 year lifespan.
- Saguaro cacti cells can occasionally mutate to generate fan-shaped crests in tangled patterns, though this is quite uncommon. Crests typically appear at the very top of the main stem.
What is the cost of a saguaro cactus?
Southwest Arizona, western Sonora, Mexico, and even a few locations in southeast California are home to saguaro cacti. They are typically found in the northern regions on slopes that face south, where the sun shines more frequently. The Saguaro Cactus is covered in protecting needles and bears a red fruit in the summer as well as tiny white blooms in the late spring.
Only in the Sonoran Desert does the suguaro cactus, also known as Carnegiea Gigantea, flourish.
A Saguaro will only grow about one to one and a half inches in its first eight years.
Moving a saguaro cactus off of private or public land without a permit is against the law in Arizona.
Saguaro cactus roots spread out like an accordion to take in as much water as they can.
Arizona’s state flower is the saguaro bloom, which blooms only after a saguaro has reached the age of 35.
SAGUARO CACTUS FACTS
The saguaro is a unique species of plant that can get rather big yet develops extremely slowly. The saguaro’s weight and height are often astounding, and the plant’s beauty is emblematic and significant to the magnificent state of Arizona.
- Arizona has rules and limitations on the gathering, harvesting, and disposal of these cactus. To learn more about the rules that apply to your region, get in touch with your neighborhood government.
- The Saguaro can survive for 150 to 200 years in the appropriate growing circumstances.
- The cactus has one major root that extends down approximately 2 feet while the remaining roots all extend out till they reach the height of the plant and only go down about 5 inches.
- Saguaro growth is particularly slow. A saguaro may only be 1.5 inches tall after a whole decade of growth. They can potentially grow to a height of 40–60 feet under the right circumstances! After a rainy season, a completely hydrated Saguaro may weigh between 3,200 and 4,800 pounds.
- Arizona legislation allows for the collection of saguaro “ribs,” which are used to create jewelry, furniture, roofs, fences, picture frames, and other things. Even the Native Americans used the ribs as water containers before the canteen was created.
HOW MUCH DOES A CACTUS COST?
According to DFRanchandGardens, the average price of a saguaro cactus in the US for 2020 is between $20 and $2,000 per foot.
The saguaro will cost less the smaller it is, according to osieOnTheHouse. However, if they are merely spears and in good condition, they typically sell for $100 or more per foot. The price of saguaros with arms is higher.
Can saguaro be eaten?
Before the summer monsoon rains arrive, saguaro fruit, which ripen during the hottest and driest time of the year, give vital moisture and nutrition to animals and insects in the Sonoran Desert.
Saguaro cacti can yield an average of 150 fruits per tree, making them a genuine desert grocery store for a few months out of the year. In late May to late June, the succulent fruit splits into three or four halves, revealing the rich red pulp and a cluster of up to 3,500 seeds high atop the saguaro’s branches.
The pulp and seeds of the cactus fruit are consumed by birds and bats, and the fallen fruit is devoured by coyotes and other creatures on the desert floor. The saguaro provided nourishment for native Sonoran Desert dwellers like the River Pima, Tohono O’odham, and Southeastern Yavapai during the hot, dry season prior to monsoon rains.
The seeds of the saguaro, which are rich in protein and fat, have a nut-like flavor and are very pleasant tasting. The fruit can be consumed both fresh and cooked, its pulp dried into cakes, and its juice made into syrup and jam. Raw or dried and crushed into flour, the seeds are consumed. Both alcoholic and nonalcoholic drinks can be prepared from juice. The O’odham and Piipaash people still gather saguaro fruit today, carrying on a long-standing tradition and reaffirming the significance of this recognizable cactus in their life.
