Crape Myrtle
Lagerstroemia indica
shrubCrape myrtle is a deciduous to semi-evergreen ornamental shrub or small tree prized for its vibrant, papery-textured flowers that bloom in summer and fall, and attractive exfoliating bark. It produces showy flower clusters in shades of pink, red, purple, and white, and displays brilliant autumn foliage before dropping its leaves. Highly valued in Southern landscapes, it's heat and drought-tolerant once established.

Establishment
First growing season (3-6 months)Young plant with sparse branching and emerging leaves; may produce few or no flowers in first year
Water regularly (2-3 times weekly in hot, dry weather); stake if needed in windy areas; light pruning to establish shape
Vegetative Growth
Spring through early summer (months 1-5 of growing season)Vigorous branching and leafy growth; plant fills out with glossy green foliage
Continue consistent watering; light pruning to shape; do NOT top or heading-back prune aggressively
Flowering
Mid-summer through early fall (July-October, 8-12 weeks)Abundant clusters of papery flowers in pink, red, purple, white, or bi-colors appear at branch tips; flowers lasting 2-3 months
Deadheading spent flower clusters encourages more blooms; ensure consistent moisture; avoid nitrogen-heavy fertilizers that promote leaf over flowers
Fall Color & Dormancy
Autumn through winter (October-March)Foliage turns brilliant shades of orange, red, or burgundy; leaves drop; decorative exfoliating bark becomes more visible
No watering needed once dormant in cold climates; in warm zones may retain leaves; do NOT prune in fall
Spring Emergence
Late April through May (depending on zone)Late bud-break as leaves emerge slowly; buds swell along branches
Wait until new growth appears before pruning dead wood; apply balanced fertilizer in early spring; avoid frost damage by not pruning too early

Harvest Tips
Crape myrtle is ornamental, not harvested for production. Deadheading spent flower clusters (panicles) extends blooming 4-6 weeks. Prune in late winter/early spring before new growth; remove weak, crossing, or rubbing branches. Avoid 'crape murder' (severe topping) which creates ugly knuckles and weakens plant. Cut branches at nodes for bouquets.
Fun Facts
- 🌱 The common name 'crape' (also spelled 'crepe') comes from the crinkled, papery texture of the petals, resembling crepe fabric.
- 🌱 Native to Southeast Asia (China, India, Japan), crape myrtle has become THE signature summer-flowering plant of the American South, thriving in heat and humidity.
- 🌱 The exfoliating bark reveals beautiful inner colors (cinnamon, tan, gray, or reddish) beneath the outer layer, making winter specimens stunning in landscape design.
