Ocotillo has always felt like a grandmother plant of the desert to me. Standing tall with her long, spiny branches reaching toward the sky, she seems to watch over the landscape and those of us moving through it. In spring, her bright red flowers leave me in awe. She’s a plant that makes me stop and pay attention.
Known botanically as Fouquieria splendens, Ocotillo also goes by Coachwhip, Candlewood, and Devil’s Walking Stick. Although her thorny branches may suggest otherwise, she is not a cactus. She belongs to the Fouquieriaceae family, which also includes the unusual Boojum tree. She is a familiar presence across the deserts of the Southwestern United States and northern Mexico, often growing on rocky slopes and well-drained desert ground.
How Ocotillo Responds to Rain
For much of the year, Ocotillo can look like a gathering of bare, thorn-covered sticks. After a soaking rain, those stems become covered in small green leaves. As water becomes scarce, the leaves fall away again, helping the plant conserve water. This cycle can happen several times a year. Rather than holding onto leaves through prolonged drought, Ocotillo responds to the water available.
The flowers follow a different rhythm. Ocotillo generally blooms in spring and can flower even when conditions are dry. Clusters of red tubular blossoms gather at the tips of the branches, attracting hummingbirds.
What Ocotillo Can Tell Us About the Land
Years ago, during a visit to Kartchner Caverns in southern Arizona, I learned that the two young men who discovered the caverns had used Ocotillo as a clue to look for limestone, where caves can form. That stayed with me. I had known Ocotillo for her appearance and medicinal uses, but I hadn’t thought about what she might tell us about the ground beneath her.
Now, when I see her growing on a rocky hillside, I sometimes wonder what’s underneath.
Indigenous Uses of Ocotillo
Indigenous communities of the Southwest have used Ocotillo for food, beverages, medicine, fencing, and shelter. The uses vary among communities, with different parts of the plant serving different needs.
For instance, the Cahuilla people ate the fresh blossoms or soaked them in water to make a summer drink. The wood also served as fuel and as fencing to help keep rodents away from cultivated crops. Accounts of Apache uses describe root preparations for fatigue and swollen limbs, while a Hualapai account describes a soothing root bath for swollen feet.
Ocotillo in Southwestern Herbal Practice
In Southwestern herbalism, Ocotillo’s inner bark is traditionally used to help move lymphatic and pelvic congestion. My mentors describe it as having an affinity for the lower abdomen and pelvic region, particularly when there is a sense of fullness, heaviness, or stagnation. Some traditional uses include pelvic congestion associated with painful menstruation, as well as hemorrhoids and varicose veins. The bark is most commonly prepared as a tincture.
The flowers are also used to make a cooling tea for hot summer days and are traditionally described as rich in vitamin C.
Ocotillo isn’t an everyday tonic for everyone. Avoid internal medicinal use during pregnancy, and consult a qualified practitioner before combining it with prescription medications, as it may affect how some medications are absorbed or processed.
Ocotillo also has a place in flower essence work, where her essence is used for responding rather than reacting, feeling protected, and finding stillness and confidence.
Respecting a Protected Desert Plant
Ocotillo is protected under Arizona’s Native Plant Law and is classified as salvage restricted. This designation regulates collection and removal; it does not necessarily mean the plant is endangered. Before collecting a plant or its living parts, check the applicable requirements with the Arizona Department of Agriculture and the landowner or managing agency.
When you are out in the desert and see those magnificent blooms, leave them for the hummingbirds, bees, and others that visit them.
You can learn a lot just by spending time with this plant. Notice where she grows and watch for the new leaves after rain.
The Grandmother of the Desert
For me, the image of a grandmother comes closest to how I feel about Ocotillo. There is strength in her presence and a feeling that she is watching over the desert and those of us moving through it.
Next time you’re out in the desert, take a closer look at her. There is so much to learn about a plant we might otherwise walk right past.
If you’d like to learn more about the plants growing around us, join me for a class or guided plant walk. My online Medicinal Plants of the Southwest class is coming in early 2027, and plant walks offer a chance to get to know these plants out in the desert. Beginners are always welcome.
