The ocotillo is a desert plant native to the southwestern United States and northern Mexico. It is characterized by its tall, spindly stems that can reach heights of up to 20 feet. The plant is not a cactus, but it has a similar appearance and is well-adapted to arid environments. During the spring, ocotillo produces bright red flowers that attract hummingbirds and other pollinators. Ocotillo thrives in sandy or rocky soils and can survive long periods of drought. Its stems are covered in small, sharp thorns, which help protect it from herbivores. The plant can quickly leaf out after rainfall, showcasing its green foliage, which helps it photosynthesize efficiently during brief wet periods.
