Lagerstroemia indica (also known as crêpe myrtle, crepeflower) is a species in the genus Lagerstroemia in the family Lythraceae, which is native to the Indian Subcontinent (hence the name indica), and also to Southeast Asia, China, Korea and Japan.
Lagerstroemia indica is an often multi-stemmed, deciduous tree with a wide spreading, flat topped, rounded, or even spike shaped open habit. Planted in full sun or under canopy, the tree is a popular nesting shrub for songbirds and wrens. Low maintenance needs make it a common municipal planting in parks, along sidewalks, highway medians and in parking lots. Like the southern magnolia, the crape myrtle has come to symbolize the American South because of its extensive planting and ability to thrive in hot, humid summer climates with regular precipitation. It is one of only a few trees/shrubs to offer brilliant color in late summer through autumn, at a time when many flowering plants have exhausted their blooms. In arid climates, it requires supplemental watering and some shade in the very hottest areas.The plant must have hot summers in order to flower successfully, otherwise it will show weak bloom and is more vulnerable to fungal diseases.
