Saguaro cactus--a tall, slow-growing mystery
"The saguaro cactus is the largest cactus in the United States, and will normally reach heights of 40 feet tall. . .
It can take 10 years for a saguaro cactus to reach 1 inch in height.
By 70 years of age, a saguaro cactus can reach 6 and a half feet tall, and will finally start to produce their first flowers.
By 95-100 years in age, a saguaro cactus can reach a height of 15-16 feet, and could start to produce its first arm.
By 200 years old, the saguaro cactus has reached its full height, reaching upwards of 45 feet tall.
Some saguaros have been seen with dozens of arms, while other cactus never produce a single one. Why this happens remains one of the desert’s mysteries."
