Creosote Bush

Creosote bush is one of the most iconic and abundant native plants we have here in the Coachella Valley.

Scientists have long admired its remarkable ability to survive the harsh desert, lifespan that can exceed an astonishing 10,000 years, as well as its significant ecological role to the local wildlife.

Botanical name: Larrea tridentata

Other names: Creosote

TABLE OF CONTENTS

Creosote is a large desert shrub that reaches about 12 feet tall and wide.

Multi-stemmed with brown to grey wood branches. Very robust root system which helps it to conserve water.

Tiny teardrop-shaped leaves are tiny and waxy, which help it to preserve water. They are dark green and turn yellow or brown when stressed.

Small, bright yellow flowers bloom in the spring. Followed by fuzzy white fruits that contain seeds.

Over many years, as the creosote matures, the old branches die off while the root system expands. Eventually, the entire old central bush will die, while new branches form their own bushes, creating a ring of creosotes that share the same genes.

When wet, the creosote bush releases a pleasant aroma called the smell of desert rain.

Helps support local wildlife, including many insects, birds, and other animals.

Extremely slow-growing. It grows one third of an inch per year.

Extremely drought tolerant. Provide supplemental water sparingly.

Mature creosote bushes are extremely hardy. They are tolerant of a very wide range of temperatures, from below 10 degrees to over 120 degrees Fahrenheit. Young creosote bushes, typically under 10 years old, die quickly under unfavorable growing conditions.

Used by various indigenous people for medicine, such as for treating wounds.

Creosote bush originates from the Southwest, USA and northern Mexico in areas that are mostly hot and dry.

Soil: Loose, well-draining soil.

Temperature: It can withstand temperatures down to 0 degrees for a short period of time and does very well in heat.

Water: Apply occasional, deep watering. Allow the soil to dry out completely between waterings. Use a moisture meter or stick your finger through the soil to gauge the moisture level. It’s better to err on the side of underwatering than overwatering.

Sun: Full sun. Partial shade in the Palm Springs region is ok.

Pests: Creosote has minimal pests. Fungal diseases are caused by root rot, dry rot, and harsh weather conditions.

Signs of overwatering: Drooping, squishy texture, browning or yellowing leaves

Signs of too little water: Drooping, shriveled leaves

Signs of too much sun: Burning, fading leaves

Signs of too little sun: Etiolation, discoloration

To propagate creosote, obtain seeds after the plant has fruited. Soak them overnight, then plant them in moist soil.
