Cultivation and History

Table of Contents

Ocotillo belongs to the Fouquieria genus, which comprises 11 desert species and is a part of the Fouquieriaceae plant family. While it is commonly known as ocotillo, it also goes by several other names like coachwhip, vine cactus, candlewood, and wolf’s candles. The name “ocotillo” originates from the Nahuátl word “ocotl,” meaning “torch” in English.

Native to regions from central Mexico to Arizona, California, New Mexico, and Texas along the US border, ocotillo thrives in arid climates on low hillsides in deserts like the Mojave, Sonoran, and Chihuahuan. A study published in the Journal of Arid Environments researched mature ocotillo shrubs and found that these long-lived plants can flower for up to 50 years in the wild. Ocotillo can grow over 20 feet tall and 15 feet wide and produces stunning reddish-orange tube-shaped flowers that bloom from late spring to summer, attracting hummingbirds and bees.

Apart from its beauty, ocotillo plays a vital role in Indigenous culture, with various Indigenous communities using it for food, medicine, and building materials. This plant is also valued in Western herbalism for its medicinal properties, with studies showing it contains compounds with antioxidant and anti-inflammatory potential.

Propagation

There are two primary methods for propagating ocotillo: from seed and by rooting cuttings.

From Seed

Propagation from seed is relatively straightforward. Sow the seeds in a location with fast-draining soil and full sunlight. Keep the soil warm and slightly moist until the seeds germinate, which usually takes up to two weeks.

From Cuttings

For propagation from cuttings, prepare a one-gallon pot with well-draining soil and take a 12-inch healthy softwood cutting from a mature plant. Remove the leaves, dip the cut end in rooting hormone powder, and plant it in the soil. It takes a few months for roots to develop from cuttings.

Transplanting seedlings or mature plants will take several years to grow to their full size, but with patience and care, they can thrive for generations.

How to Grow

Ocotillo thrives in hot and dry climates with full sun exposure and well-drained soil. It can withstand temperatures down to about 10°F and requires minimal water once established. With little maintenance and no need for fertilizer, ocotillo can grow effortlessly in harsh arid conditions.

Growing Tips

To ensure the successful growth of ocotillo, follow these simple tips:
– Grow in hot and dry climates.
– Plant in full sun and well-drained soil.
– Avoid overwatering established plants.

Pruning and Maintenance

While ocotillo requires minimal maintenance, avoid unnecessary pruning as it can hinder flower production. Only prune dead or damaged stems, and refrain from topping the plants as it can affect their natural growth.

Where to Buy

Ocotillo plants are widely available and popular in cultivation. Local nurseries in desert climates are ideal places to find these stunning plants.

Managing Pests and Disease

Ocotillo is resilient and not prone to any specific diseases. The main pest to watch out for is scale, which can be controlled effectively if identified early.

Best Uses

Ocotillo is an excellent addition to desert gardens, attracting pollinators like hummingbirds and beneficial insects. It pairs well with other desert plants and can be used for defensive purposes due to its strong branches. However, caution is advised due to its sharp spines, especially around pets and children.
