Ocotillo is a semi-succulent desert shrub, native to the Southwest US and northern Mexico, with tall whip-like green stems and bright red flower spikes after rain. It is best grown in full sun with very little water and fast-draining, rocky soil.

About
Fouquieria splendens, commonly known as ocotillo, is a plant indigenous to the Mojave, Sonoran, Chihuahuan and Colorado deserts in the Southwestern United States (southern California, southern Nevada, Arizona, New Mexico, Texas), and northern Mexico (as far south as Hidalgo and Guerrero).
Ocotillos look desiccated on the outside, but they are semi-succulent; it is more closely related to the tea plant and blueberries than to cactuses. It regenerates leaves after rainfall. They can be planted as garden ornamentals.
How to grow it
Ocotillo can be planted year-round with care. Ideal plants have been grown in pots from stem cuttings and from seed. Transplanting large bare-root plants has marginal success. They should be planted to the original growing depth and, as with cacti, in their original directional orientation: the original south side of the plant, which has become more heat- and sunlight-resistant, should again face the brighter, hotter southern direction. If their direction is not marked, success is again limited.
Uses
Individual ocotillo stems are sometimes used as poles as a fencing material in their native region, and often take root to form a living fence.
