    The saguaro is an iconic spiny cactus tree of the Sonoran Desert. It may grow to about 50 feet (in rare cases much larger) with branches. Stems are green, with 12-30 sharply marked ribs. Flowers are white and appear near the tips of the stems. Fruit is red, fleshy, edible, and dehiscent. Provide strong light and excellent drainage in cultivation. Drought tolerant when established. Mature plants can be really striking. This is the only species in its genus.

    Found in subtropical Arizona and Sonora (34°N to 26°N) and on some islands in the Gulf of California, but not found in Baja California, where it is replaced with the cardón gigante (Pachycereus pringlei). Also found in a few small populations in southeastern California near the Arizona border. Relatively common in habitat and often found growing on rocky or sandy substrates. Its northern extent (34°N) and maximum altitude (1350m) reflect its limits in cold tolerance; its western extent (just west of the Colorado River) is thought to be limited by summer rainfall. Protected by law in Arizona.

    This plant may be easy to confuse with the giant cardón (Pachycereus pringlei), especially when young. Geography is a useful clue to distinguish them (Arizona and Sonora are saguaro country; Baja California is the home of the cardón). Saguaros tend to grow slower than cardones, but neither is likely to get near its full size in your lifetime, grown from seed (as these plants are propagated). Saguaros tend to be less massive and branch higher up than cardones, and their flowers are different.
