Answer: Well, whoever told you Lantana is perennial is correct - and incorrect! It is perennial in warmer parts of Texas, but in your area (USDA Zone 7B) it's grown as an annual. The plants can be overwintered indoors, and although the tops look dead, the roots may still be alive. Water the pots and set them in a bright room out of direct sun - they may send up green shoots. Do not fertilize, and water them sparingly. If they don't make it, you can plant seeds outside in early spring.
