Answer: Both lantana and crape myrtle need winter protection in your growing region. Since they won't survive outdoors, you can try overwintering them indoors. Treat them just as you would any other sun-loving tropical; provide bright light, mist daily to increase humidity and counteract dry indoor air, and water as necessary. Don't fertilize, and don't expect flowering during the winter months. When the weather warms, take them back outdoors and they should make up for lost time.
Best wishes with your plants!
