Why are crape myrtles so popular in the South?
Most crape myrtle varieties thrive in zones 6-10, grow quickly, tolerate different soil types and love heat and humidity. Grown as a large shrub or small flowering tree, most crape myrtles bloom all summer long, and their foliage often changes color in the fall. Exfoliating bark also adds interest to the landscape.
To keep them looking their best, crape myrtles should be pruned in the winter or early spring.
