Light: Morning sun with afternoon shade is ideal in Phoenix. Strong light enhances purple color; intense afternoon sun can scorch foliage, especially in reflected heat.
Water: Low to moderate water once established. Water deeply, then let the upper few inches of soil dry. Water more frequently during extreme summer heat and in containers; reduce watering in winter.
Soil: Well-drained soil; tolerates sandy or gravelly soil. Add modest organic matter where soil is poor, and avoid soggy conditions.
Mature size: 12–18 inches tall and 2–3 feet wide, spreading farther where stems root.
Bloom: Small flowers appear intermittently from spring through fall in warm weather.
Evergreen / deciduous: Evergreen in frost-free locations; frost can kill foliage and stems, with regrowth from surviving roots in spring.
Growth rate: Fast during warm weather with adequate moisture.
