Lagerstroemia indica (crape myrtle, crepe myrtle, crepeflower) is a species in the genus Lagerstroemia in the family Lythraceae.

Native to the Indian Subcontinent (hence the name indica), and also to Southeast Asia, China, Koreaand 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.

The bark is a prominent feature being smooth, pinkish-gray and mottled, shedding each year. Leaves also shed each winter, after spectacular color display, and bare branches re-leaf early in the spring; leaves are small, smooth-edged, circular or oval-shaped, and dark green changing to yellow and orange and red in autumn.

Flowers, on different trees, are white, pink, mauve, purple or carmine with crimped petals, in panicles up to 9 centimetres (3 12 in).

Lagerstroemia indica is frost tolerant, prefers full sun and will grow to 6 metres (20 ft) with a spread of 6 metres (20 ft). The plant is not picky about soil type but does require good drainage to thrive. Once established it is also quite drought hardy, though it benefits from the occasional deep watering during the summer months.

15 hybrid cultivars have been developed between L. indica and L. faueri by the US National Arboretumfor increased cold-hardiness and resistance to disease, all given the names of Native American tribes.There are also dwarf cultivars of indica x faueri cross-breeds and regular L. indica species, which grow between 2 and 5 feet (1.5 meters).
