Creosote Bush (Larrea tridentata) exists as a drought-enduring shrub which naturally appears throughout North American desert regions. The plant grows between 90 and 300 cm in height and spreads from 150 to 300 cm while its small resinous leaves decrease water loss by half. Yellow flowers bloom between March and August. The seeds of Creosote Bush demonstrate limited success in sprouting with rates between 10 – 20%. The plant gains absorption moisture down to a depth of 100 cm. The shrub grows optimally in soils with a pH range of 7 – 8.5 that are alkaline in nature. It withstands temperatures from -10°C to 50°C. The annual rainfall level needed for Creosote Bush survival is less than 20 cm. Allelopathic chemicals released by this plant prevent a 60% growth reduction among surrounding plants. This desert plant reaches exceptional longevity when it survives past 100 years thus becoming one of the oldest plants.
Characteristic | Description |
Size | Typically 3 to 10 feet tall, with a dense, bushy form. |
Appearance | Dark green, waxy, needle-like leaves with a distinctive, aromatic scent when crushed. |
Spines | No spines; instead, it has small, leathery leaves. |
Flowers | Yellow, five-petaled flowers that bloom in late spring to early summer. |
Fruits | Small, round, fuzzy fruits that contain seeds, typically not edible. |
Root System | Deep, extensive roots that allow the plant to access deep water sources. |
Lifespan | Can live for several decades, often up to 100 years or more. |
Habitat | Native to the southwestern United States and northern Mexico, thriving in arid deserts and rocky soils. |
Water Storage | Stores water in its stems and roots, highly drought-tolerant. |
Growth Rate | Slow, growing about 1 to 2 feet per year. |
Flowering Time | Blooms in spring and summer, with occasional blooms after rainfall. |
Reproduction | Seeds are dispersed by wind and animals, with germination triggered by rainfall. |

What Type of Plant is the Creosote Bush?
The evergreen shrub Creosote Bush (Larrea tridentata) belongs to the Zygophyllaceae family. The plant occupies arid environments while developing thick plant groupings. The waxy tiny leaves of this plant help it conserve water through reduced evaporation. Yellow flowers bloom seasonally. The plant emits a strong, resinous scent. The plant reproduces by seeds and root sprouts as it conquers arid land areas using its resilient desert-tolerant features.
How to Grow Creosote Bush, from Seed, Propagate, and Transplant it?
The habitat for Creosote Bush (Larrea tridentata) consists of sandy and well-drained soils. To germinate seeds requires exposure to light and 30% humidity in the environment. Stratification for 30 days improves success. Seeds need to be placed at depths from 2 to 3 cm in order to protect the roots from drying out. Cuttings of 15 – 20 cm root in loamy soil with 85% success. Gettings establish as new plants when the transplants measure under 50 cm within a time span of 60 days. Proper airflow is possible when plants are spaced 200 – 250 cm apart. A 5 cm mulch layer retains soil moisture. Root run develops 120 cm long which helps to stabilize the soil environment. Water absorption efficiency reaches 65%. Plant growth receives a 40% increase in nutrient absorption from the integration of nitrogen-fixing bacteria. The plant grows at a gradual pace with an average yearly growth between 10 and 25 centimeters.
How to Get Rid of Creosote Bush?
The removal of Creosote Bush (Larrea tridentata) requires three successive steps including cutting, digging and soil treatment. Plant growth suppression reaches 60 percent when individuals trim plants at ground level. Removal by digging serves to remove roots down to depths of 120 cm from the soil. The use of herbicide containing 2% triclopyr boosts the total kill percentage to 80%. Soil nutrients experience damage as an effect of burning dry shrubs. Repeated mowing controls spread. The root structure becomes weaker when soil moisture rises higher than 30%.
How does the Creosote Bush Survive in the Desert?
Creosote Bush (Larrea tridentata) can survive in the desert by extending its root system down 120 cm to access water. The waxy characteristics of tiny leaves perform a 50% function in decreasing water loss. Plants utilize allelopathic chemicals to minimize competition for nutrients among themselves. Resin-coated stems resist extreme heat. It tolerates temperatures from -10°C to 50°C. The tight plant growth pattern captures air moisture which allows the plants to thrive better in dry climates.
Does Creosote Come from the Creosote Bush?
The Creosote Bush (Larrea tridentata) does not produce the chemical compound Creosote. The plant generates resinous oils although it does not contain authentic creosote substances. Industrial wood-tar creosote exists as a product derived from distilling both coal and wood-tar substances. The medicinal properties of Creosote Bush resin differ chemically from industrial creosote which functions as a preservative.
Are Creosote Bushes Toxic or Poisonous to Humans and Dogs?
A substance known as nordihydroguaiaretic acid inside Creosote Bush (Larrea trdentata) can damage liver and kidneys when consumed in large quantities. The consumption of either stems or leaves from Creosote Bush causes dogs to experience poisoning that results in vomiting and diarrhea. Prolonged exposure irritates human skin. The plant’s dense resinous oils create an unpleasant flavor that deters most animals from eating it.
