Hybrid Palo Verde

Parkinsonia hybrid

Also known as: Desert Museum Palo Verde

Hybrid Palo Verde

A thornless palo verde hybrid combining the best traits of native species with an urban-friendly, clean form.

Frost hardy to about 15°F in low and mid desert, with fast warm-season growth.

AMWUA Notes

Very low water; a thornless, nearly seedless hybrid ideal near pools, though it should not be overwatered.

Care Guide

💧Watering

Deep-soak weekly the first summer, then monthly once established; keep watering lean to avoid weak, floppy growth.

✂️Pruning

Prune in late winter to build strong scaffolds; this fast, vigorous grower needs structural pruning to prevent limb breakage, and thin for wind.

🌱Fertilizing

No fertilizer needed; overfeeding and overwatering cause floppy growth on this nitrogen-fixing tree.

🛡️Pests

Palo verde root borer larvae are the main concern; few others.

☀️Seasonal Notes

Long, heavy yellow bloom from spring into summer; drought- to semi-deciduous with green photosynthetic bark.

Soil, Feeding & Propagation
