Organ Pipe Cactus
|
There are 28 different species of cacti in the monument, ranging from the giant saguaro to the miniature pincushion. These cacti are all highly adapted to survive in the dry and unpredictable desert. They use spines for protection and shade, thick skin and pulp to preserve water, unique pathways of photosynthesis at night, and hidden under their skin are delicate to sturdy wooden frames holding them together.
Organ pipe cactus originated in the warm, dry tropics. When the global climate warmed at the end of the last Ice Age, the cactus slowly began migrating further north. It arrived in the Sonoran Desert only about 3500 years ago.
Organ Pipe Cactus can live to over 150 years in age, and will only produce their first flower near the age of 35.
