That means that you can start growing crepe myrtle trees outdoors, but you'll have to think of them as perennials. They will probably die back to the ground over the winter, then resprout in spring.
Crape myrtle seeds will germinate most any time, but they will do best in early spring when the days are lengthening. Gently press them into the surface of a light, moist potting medium. Cover with a layer of milled sphagnum moss, and mist until damp.
