Saguaro cacti are a necessary component of a Sonoran Desert journey for hikers in Arizona. However, one listener asked why on her treks she encounters significantly more juvenile, “saguaro-like” cactus than actual fledgling saguaros.
The saguaro, which grows only in the Sonoran Desert, is possibly the best plant to represent this barren region.
Marty Wojciechowski, an expert on cacti at Arizona State University, thinks the listener’s “pseudo-saguaros” may actually be another kind of cactus, such a young barrel.
“Young saguaros are extremely challenging to come by. Typically, they are hidden by a bush. They usually grow somewhat protected by larger plants, so you don’t usually see them until they reach a height of around a foot “Wojciechowski added.
Confusion may be increased by the fact that saguaros grow very slowly and can take up to a century to develop arms.
How can you tell whether your saguaro cactus is small?
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!
How can you differentiate a saguaro from a regular cactus?
Recognizing Features 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.
