Leonotis leonurus
Light: Full sun to light shade; afternoon shade is beneficial in Phoenix, especially near hot walls or pavement.
Water: Low to moderate water once established; water deeply, then let the upper several inches of soil dry. Provide supplemental irrigation during prolonged Phoenix summer heat; reduce watering in winter.
Soil: Well-drained sandy or loamy soil; tolerates relatively poor soil but dislikes waterlogged roots.
Mature size: 4–6 feet tall and wide; occasionally taller with ample water and mild winters.
Bloom: Typically late summer through fall, sometimes extending into winter in frost-free locations; extreme summer heat may reduce flowering.
Evergreen / deciduous: Evergreen in frost-free conditions; may become semi-evergreen or die back after freezes in Zone 9b.
Growth rate: Fast during warm weather with adequate moisture.
