Answer: The common morning glory is an annual and will die down at the end of the growing season. If you're growing the Ground Morning Glory (Convolvulus mauritanicus), it is hardy to zero degrees F and should be fine in your garden without a protective mulch. If your garden experiences colder temperatures, cover the plant with a mound of dried leaves or even straw for the duration of the winter and uncover it in spring. Best wishes with your landscape!
