Lagerstroemia indica 'Dynamite'
Light: Full sun for best flowering, ideally at least 6 hours daily. In Phoenix, light afternoon shade can reduce heat stress; avoid intense reflected heat from west-facing walls.
Water: Moderate water needs in Phoenix. Water deeply and regularly during establishment and summer heat, allowing the upper few inches of soil to dry between irrigations. Reduce watering substantially during winter dormancy.
Soil: Well-drained soil; tolerates sandy or clay soils if drainage is adequate. Prefers slightly acidic to neutral conditions but can grow in alkaline desert soils with attention to nutrient availability.
Mature size: Typically 15–25 feet tall and 10–20 feet wide.
Bloom: Large flower clusters from late spring or early summer into early fall, with peak flowering in summer. Blooms on new growth.
Evergreen / deciduous: Deciduous.
Growth rate: Moderate to fast with adequate water, generally about 1–2 feet per year.
