Creosote Bush

Name: Creosote Bush
Brand: Outdoor Dream Builders

Larrea tridentata

The iconic desert shrub known for its distinctive rain-triggered fragrance, supporting bees and wildlife across the Sonoran Desert.

Hardy in USDA zones 8-11; the defining shrub of three North American deserts, it withstands extreme heat, drought, and mid-desert frost with ease.

AMWUA Notes

The archetypal very-low-water desert native despite its high listing; needs essentially no irrigation and is one of the longest-lived plants on Earth.

Care Guide

💧Watering

Despite the high listing, established plants are among the most drought tolerant of all desert shrubs and need water only monthly at most; occasional deep soaks keep them denser and greener.

✂️Pruning

Prune minimally, thinning to reveal the sculptural branch structure; avoid shearing this slow, characterful shrub, which is prized for its open natural form.

🌱Fertilizing

Never fertilize; it thrives in the poorest desert soils and can live for centuries.

🛡️Pests

Effectively pest-free; its resinous foliage is chemically defended against nearly all browsers.

☀️Seasonal Notes

Evergreen with resinous leaves that release the iconic desert rain scent; small yellow flowers and fuzzy white seed capsules appear mainly after summer rains.

Soil, Feeding & Propagation

🪨Soil

The poorest rocky, gravelly desert soils; thrives in caliche and alkaline pH 7.5-8.5.

💧Drainage

Needs sharp, fast-draining soil.

🌱Nutrient Needs

None — thrives in lean desert soil without fertilizer.

🌰Propagation

From seed (difficult; needs scarification and treatment); very slow.

📐Spacing

5-6 ft

🌳Roots & Placement

Deep, non-aggressive roots; mildly allelopathic but no hardscape risk.

Placement Tips

•A rounded 6 ft shrub; space 5-6 ft apart or use singly as an iconic native specimen.
•Essential for authentic Sonoran and restoration designs, pairing with saguaro, bursage, and wildflowers.
•Low litter and thornless form make it pool-friendly, and its scent after irrigation is a feature.
•Plant in full sun with sharp drainage; it is effectively immortal and needs almost nothing once set.
