About Crape myrtle

Lagerstroemia calyculata, known as ស្រឡៅ (Sralao) in Cambodia, is a medium to large deciduous tree, valued for its spectacular bloom of lavender-pink to purple flowers in panicles. Its smooth, peeling bark adds visual interest throughout the year, making it an excellent ornamental tree for parks, large gardens, and avenue plantings in tropical and subtropical climates.

Care tips

It thrives in full sun for abundant flowering and prefers well-drained, slightly acidic to neutral soil. It is drought-tolerant once established but benefits from regular watering during dry spells, especially when young. Protect young plants from severe frosts, though mature specimens can tolerate brief temperature drops. Avoid overwatering and waterlogged soils, as this can lead to root rot.
