Red Justicia

Justicia candicans

Red Justicia

A compact Arizona native shrub with vivid bright red flowers from fall through spring that are a favorite of hummingbirds.

Hardy in USDA zones 9-11; an Arizona native tolerant of low-desert heat, especially with some shade, and root-hardy through typical frosts.

AMWUA Notes

A higher-water native that welcomes afternoon shade; provides valuable cool-season hummingbird color in filtered-light spots.

Care Guide

πŸ’§Watering

Prefers regular water, deep-soaking every 7-10 days in summer, especially with the afternoon shade it appreciates; keep it from drying out completely.

βœ‚οΈPruning

Head back lightly after the main bloom to keep it compact and full; it responds well to shaping but does not need heavy pruning.

🌱Fertilizing

A light spring feeding supports its lush growth.

πŸ›‘οΈPests

Free of significant pests.

β˜€οΈSeasonal Notes

Semi-evergreen; bright red flowers appear from fall through spring, offering cool-season hummingbird nectar, and it can thin in a hard frost.
