White Lagerstroemia indica (White Crape Myrtle)
Scientific Name: Lagerstroemia indica
Common Name: White Crape Myrtle
Family: Lythraceae
Origin: Native to Asia (especially China and Korea)
Type: Deciduous flowering shrub or small tree
Growth Habit: Can be grown as a bush or trained into a small tree
Height: Typically ranges from 2 to 5 meters (can vary by cultivar)
Flowers: Pure white, crepe-paper textured blooms in clusters
Blooming Season: Long flowering period – summer to early fall (up to 3–4 months)
Leaves: Glossy green; turn yellow, orange, or red in autumn
Bark: Smooth, exfoliating bark in shades of tan and cinnamon – highly ornamental in winter
Light Requirements:
Full sun is essential for best flowering (at least 6 hours/day)
Shaded areas reduce the number and quality of blooms
Water Requirements:
Water regularly during the first year until well established
After establishment, it becomes drought-tolerant
Let the top layer of soil dry out between waterings
Avoid constant soggy soil
Soil Conditions:
Prefers well-draining soil, but adapts to a wide range (clay, loam, sandy)
Tolerates slightly acidic to neutral pH
Good drainage is key to preventing root diseases
Fertilization:
Fertilize in early spring with a balanced fertilizer
Avoid excessive nitrogen, which can reduce blooms and encourage foliage growth
A light application in mid-summer may promote a second bloom flush
Pruning:
Prune in late winter or early spring to shape and remove old wood
Avoid aggressive topping (“crape murder”) which weakens the plant
Deadheading (removing spent flowers) can extend bloom period
Pests and Diseases:
Powdery mildew is a concern in humid climates – use resistant varieties
May attract aphids and cause sooty mold
Treat pests with insecticidal soap or horticultural oil if needed
Keep good air circulation around the plant
