Saguaro cactus (Carnegiea gigantea) is a popular landscape cactus in our region. Often used as a centerpiece in desert gardens, it is also popular for planting in public common areas and in roadway medians.
Rather than buy one large Saguaro, I chose four smaller ones (each about four feet tall) because of the low transplant success rate of large specimens. Saguaros are very slow growing, so they are expensive to purchase, selling for about $100 a foot. I stopped at $2000 for my four.
My brother took this photo of a Saguaro on some raw desert land that he owns. Since it has more than five arms, it is probably approaching 200 years old.
Saguaro cactus, pronounced Sah-wah-roh, grows only in the Sonora Desert.
Its flower, which blooms late April to June, is the Arizona State Flower.
Saguaros can live up to 200 years and reach 50 feet high.
A Saguaro with more than five arms is probably around 200 years old. In the desert, it does not grow arms until it is about 100 years old.
A mature Saguaro can weigh six tons, which is mostly stored water.
Only one seed in 50 million will germinate. Of those, only a few will become a seedling and even fewer will become an adult cactus.
This huge cactus has a taproot that is only about three feet long, and many large roots that grow downward only about one foot deep. Many smaller roots run a distance equal to the cactus’ height.
