A great place to see them is on Tumamoc Hill, a butte which looms over the city of Tucson. Hundreds of people walk the three mile round trip every day. Everyone is super friendly and shares information about the saguaros. That’s how I learned about 'Ramona,' whom I was told is the most loved cactus on the Hill. So many people have given her a hug that she no longer has spines on her lower trunk. It’s impossible to give Ramon a hug without smiling.
A threat to saguaros is the invasive buffelgrass. The volunteers of the Sonoran Desert Weedwackers meet three times a month to pull this highly flammable grass. These dedicated volunteers have cleared thousands of acres of buffelgrass over the past 25 years.
Here are some facts I learned about them from a park ranger on a sunset walk at Saguaro National Park:
Saguaros only grow in the Sonoran Desert and range from central Arizona to Sonora, Mexico.
To procreate, they grow large white flowers on the top of their heads and ends of their arms which are pollinated by bees, bats, and birds. The more arms they grow, the more flowers, the more opportunities to ensure their DNA continues into the future.
The next stage is a red fruit. People have eaten them for centuries. Tastes like chicken (only kidding:-)
If a seed is lucky enough to land in a suitable spot, it takes five years before a cute little saguaro can be seen.
They start producing flowers at around 35 years of age.
Arms start growing between ages 60 and 80. Most have two to six arms. The record holder is a saguaro named 'Shiva' that’s located in the Ironwood Forest and has a whopping 40 arms.
They live to around 150 years and can reach 30 or 40 feet tall. According to the Guinness Book of World Records, an armless saguaro grew to 78 feet.
Their roots are shallow but are as wide as the cactus is tall so that a lot of root.
