The magnificent Saguaro Cactus grows the state flower of Arizona. This cactus is composed of a tall, thick, fluted column that grows from 18 to 24 inches in diameter with several large branches curving upward and downward in a distinctive formation frequently likened to natural sentries. Its flowers are creamy white with yellow centers that open about 3 inches in diameter. As the following description by Dad reveals, the blossoms only open during the cooler desert nights and close again by the next midday.
