Yes, it stays outside in winter. The leaves die if they're exposed to much frost, but the stems survive, and sprout again in spring. In a severe winter the top may all die, but it should grow bacdk from the roots. It's also very easy to take cuttings, and keep a spare plant indoors for winter, which will quickly grow large again during the summer. The plant in this picture was only about 3 inches tall in spring.

Re Ipomoea indica:
did you leave it out for the winter and how did it cope ?
