Brittlebush

Name: Brittlebush
Brand: Outdoor Dream Builders

Encelia farinosa

An iconic Sonoran Desert native with silver foliage and bright yellow daisy flowers that support bees, butterflies, birds, and mammals.

Hardy in USDA zones 8-11; a quintessential low-desert native that handles extreme heat and mild frost, though hard freezes can damage top growth.

AMWUA Notes

One of the most iconic very-low-water Sonoran natives; needs no irrigation once established and can rot from overwatering.

Care Guide

💧Watering

Extremely drought tolerant; water only monthly or not at all once established, and avoid overwatering, which shortens its life and causes rot.

✂️Pruning

Shear back by half after the spring bloom to remove spent flower stalks and keep the silver mound dense; the short-lived plant looks ragged and woody if never cut back.

🌱Fertilizing

Never fertilize; it thrives in poor, rocky desert soil.

🛡️Pests

Free of serious pests.

☀️Seasonal Notes

Drought-deciduous with silvery leaves that curl and drop in heat and drought; it blankets itself in yellow daisies from late winter through spring, going dormant in the hottest, driest months.

Soil, Feeding & Propagation

🪨Soil

Poor, rocky, fast-draining 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; self-sows abundantly.

📐Spacing

3-4 ft

🌳Roots & Placement

Shallow, non-aggressive roots; no hardscape concern.

Placement Tips

•Compact at about 3 ft; space 3-4 ft apart and mass for the classic golden spring hillside effect.
•A foundational filler among saguaro, ocotillo, and boulders in any Sonoran-native design.
•Low litter suits pool areas, but deadhead the spent stalks for a clean look.
•Requires full, hot sun and excellent drainage; it is short-lived but self-seeds readily.
