how old are cactuses
A saguaro must be 35 years old before it can grow any flowers. The saguaro cactus is like the plant of perpetual youth â it is only considered an adult when it is 125 years old, and saguaros generally die when theyâre 150-175 years old. Lucky, or particularly youthful cacti, may live over 200 years. The bloom of the saguaro is Arizonaâs state flower.
