Ocotillo and Cholla Cactus

The Ocotillo is abundant in the Southwest because the soil is well drained on rocky slopes, mesas, out washed plains and desert grasslands. The ocotillo is deciduous, drought tolerant shrub. From its root crown it grows stems that can be any where from 9 to 30 feet tall.  The stems are covered with spines that can be 1.5 inches long. The leaves of the shrub are thick and leather like and grow several times in the growing season depending on the amount of rainwater available. The leaves are narrow 2-inch ovals, which can sprout within 3 day of a rainfall. The leaves turn brown and fall off when water is scarce.
