Cacti of the Monument
There are 31 species of cacti in the monument, ranging from the giant saguaro to the miniature pincushion. These cacti are 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.
Day or night, the summer display of different cactus blooms is one of the desert's flashiest spectacles, as the brilliant flowers of yellow, red, white, and pink bring color to the landscape. It is a show upstaged only by the springtime explosions of gold poppies, blue lupines, pink owl clover, and other annuals after a wet winter.
