Thunderstruck™ Coral Boom™ Crape Myrtle

Coral-Pink Blooms All Summer Long — In a Compact, Manageable Size

Thunderstruck™ Coral Boom™ Crape Myrtle (Lagerstroemia 'PIILAG-IV') delivers everything that makes crape myrtles iconic — massive, showy flower clusters, exfoliating bark, brilliant fall color, and exceptional heat and drought tolerance — in a compact 6–10 ft form that fits beautifully in smaller landscapes, mixed borders, and large containers. Its vivid coral-pink blooms open in early summer and continue through fall, making it one of the longest-blooming flowering trees available. Part of the award-winning Thunderstruck™ series, Coral Boom™ is selected for superior disease resistance, compact habit, and prolific, repeat blooming.

Why Thunderstruck™ Coral Boom™ Stands Out

• Exceptional bloom duration — vivid coral-pink flower clusters from early summer through fall; one of the longest bloom seasons of any flowering tree
• Compact, manageable size — 6–10 ft tall × 5–8 ft wide; fits in smaller landscapes where standard crape myrtles would overwhelm
• Superior disease resistance — bred for resistance to powdery mildew, the most common crape myrtle disease
• Stunning multi-season interest — coral-pink summer blooms, brilliant orange-red fall foliage, and attractive exfoliating cinnamon-brown bark for winter interest
• Drought-tolerant once established — thrives in heat and dry conditions; one of the most heat-resilient flowering trees available
• Pollinator magnet — large flower clusters attract butterflies, bees, and hummingbirds throughout the bloom season
• Container-friendly — compact size makes it suitable for large patio containers (25+ gal)

Hardiness & Growing Zones

• USDA Hardiness Zones: 6–10
• Zone 6: Hardy in-ground; may die back to the ground in severe winters but regrows vigorously from the roots in spring; plant in a sheltered location and mulch heavily around the base before first frost
• Zones 7–8: Ideal conditions; vigorous growth with prolific, continuous blooming from early summer through fall
• Zones 9–10: Thrives in heat; may bloom earlier (late spring) and continue even longer into fall; one of the best flowering trees for hot, humid climates
• Sunlight: Full sun (6–8+ hours required; more sun = more blooms and better disease resistance)
• Soil: Adaptable to most well-drained soils; tolerates clay, sandy, and loamy conditions; avoid waterlogged sites
• Mature size: 6–10 ft tall × 5–8 ft wide
• Bloom time: Early summer through fall (June–October in most zones)

Planting & Care Tips

Plant in the sunniest spot available — crape myrtles bloom most prolifically in full sun, and shade significantly reduces flowering and increases disease susceptibility. Water deeply during the first growing season to establish roots, then reduce frequency — established crape myrtles are quite drought-tolerant. Fertilize once in early spring with a balanced slow-release fertilizer. Deadhead spent flower clusters to encourage a second or third bloom flush. Avoid “crape murder” (heavy topping) — Thunderstruck™ Coral Boom™ has a naturally compact, attractive form that requires only light pruning to remove crossing branches and spent blooms.

Available Sizes

• 2–3 ft. (3 Gallon) — well-rooted young tree; most economical
• 3–4 ft. (3 Gallon) — established specimen; faster to first bloom display
• 4–5 ft. (3 Gallon) — largest available; immediate landscape presence; may bloom first season after planting
