I've heard that it's a viable way to root Crepe Myrtle. Anyway, it's worth a try with some rooting hormone. Gardengater
Crepe Myrtle is one of the easiest to propagate from cuttings. Make sure you cut it just below a leave node, that is where the new roots will come from. Use Rooting Hormone on the cut ends, stick them in sand and water them. Once you see new buds growing you can gently tug on the plant to see if there are strong roots, if so then they can be transplanted to a pot of soil or put them in the ground depending on your weather.
