Did You Know?
The saguaro grows only in the Sonoran Desert around Tucson, reaches about 12 metres and can live 150 to 200 years — but does not grow its first arm until somewhere around age 70. Two national park units protect them either side of the city.
The clock: Arizona does not observe daylight saving, so Tucson matches Los Angeles in summer and Denver in winter without moving its own clocks.
