Morning Glories

Question

I was wondering if it is possible for Morning Glories to come back year after year? We have received conflicting answers. Our plants have very thick stems at the bottom.

Answer 1

In warm climates the plants can be perennials and also reseed easily.
In colder climates the plant is an annual and would need to be replanted each year.
