Crepe myrtles bloom in the summer. The new wood of the tree usually yields the blooms, so pruning in the winter or early spring is recommended.
The queen's crepe myrtle (Lagerstroemia speciosa), which generally only grows in the southern United States, blooms from June to July. The more common L. indica varieties of crepe myrtle bloom throughout the whole summer. Some species, such as the Japanese crepe myrtle (L. fauriei), have the chance to bloom twice: once during the early summer and again in the late summer. After the first bloom, the spent flowers can be carefully removed to promote a second, lighter bloom.
