Crape Myrtles (Lagerstroemia indica) are a popular ornamental shrub or small tree. While known primarily for their summer flowers, Crape Myrtles also offer great fall color and handsome exfoliating bark. There are many cultivars available, ranging from dwarf sizes to tree-type.
Tree-type Crape Myrtles exhibit variable growth habits– some exhibit a vase-like form, while others will develop a more rounded shape. All are multi-stemmed plants, and are tolerant of heat and dry conditions once established. Crape Myrtles bloom on new growth, which has led some to butcher or “top” these plants to encourage flowering. The result is a stunted tree with poorly developed form. The images below from the Clemson University Extension illustrate the benefits of correct pruning.

The following is a slide show of Tree-Type Crape Myrtles showing flower colors for comparison. Tree-Type Crape Myrtles can reach sizes between 23-33′, though those dimensions are more likely in the South. Another slide show (same pictures but with a bit more info) can be found here.
The next slide show is for the Intermediate group of Crape Myrtles, which can reach sizes between 13-20′ (again, larger sizes are achieved in the South).
