Foothills Palo Verde

Name: Foothills Palo Verde
Brand: Outdoor Dream Builders

Parkinsonia microphylla

A sculptural Sonoran native with luminous lime-green bark and a canopy of bright yellow blooms that lights up the spring desert.

Cold hardy to about 10-15°F, a low- and mid-desert native with excellent heat and frost tolerance.

AMWUA Notes

Extremely low water; an iconic slow-growing Sonoran native that needs almost no supplemental irrigation once mature.

Care Guide

💧Watering

Deep-soak monthly in summer while establishing; needs essentially no supplemental water once mature.

✂️Pruning

Prune minimally to preserve the natural sculptural form; avoid heavy cuts since the green bark photosynthesizes. Work in late winter.

🌱Fertilizing

No fertilizer needed; a tough native.

🛡️Pests

Palo verde borer and mistletoe are the main concerns.

☀️Seasonal Notes

Pale-yellow bloom in late spring, a bit later than blue palo verde; drought-deciduous with green twigs and light litter.

🪨Soil

Sharply draining rocky, gravelly, or decomposed-granite soil; thrives on lean 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

Grown from scarified seed; very slow-growing, so start from established stock

📐Spacing

25–30 ft

🌳Roots & Placement

Deep, non-aggressive roots; keep 15+ ft from pools for thorns and seasonal litter

•Broad 30 ft slow sculptural native with a signature Sonoran look; give it open space.
•Small thorns and seasonal litter make it a poor poolside choice; keep 15+ ft from pools.
•Slow-growing, so start with an established plant, and pair it with saguaro as a classic nurse tree.
•Full sun; a keystone habitat tree for native and pollinator gardens.
