Lagerstroemia indica 'Dynamite'
Light: Full sun, ideally at least 6 hours daily. Light afternoon shade can help in Phoenix’s hottest exposures; avoid west-facing reflective walls.
Water: Moderate water in Phoenix. Water deeply and regularly during establishment; afterward, irrigate deeply as the upper several inches of soil dry. Increase watering during extreme summer heat; reduce substantially in winter.
Soil: Well-drained soil; tolerates sandy, loamy, or clay soils if drainage is adequate. Slightly acidic to neutral soil is preferred, but alkaline soil is tolerated unless nutrient deficiencies develop.
Mature size: Typically 15–25 feet tall and 10–20 feet wide, depending on growing conditions and training.
Bloom: Summer into early fall, typically June through September in Phoenix; flowers form on new growth.
Evergreen / deciduous: Deciduous.
Growth rate: Moderate to fast with adequate irrigation.
