Nature’s water tower

Saguaro (sa-WAH-ro) are huge tree-like cacti found only in the Sonora Desert. They may reach 40-60 feet tall and live over a hundred years. White flowers bloom in the spring but only open at night. The Saguaro is pleated, and these expand with water after a rain. The pleats contract as the cactus uses the stored water during dry periods. The NC Zoo's Desert collection contains a legally wild collected (permitted) specimen of this plant.
