crape myrtle

many colors and sizes blooms all summer can be trained as tree or large shrub

This is a good example of what not to do with crape myrtle.

The popular misconception is that your should prune a crape myrtle to force more booms because they  bloom on new wood.   However, the new growth does not have the strength to support the blooms. The new branches weep  under the weigh of the flowers, and the character of a beautiful tree is mangled.
