Answer: Your Heavenly Blue Morning Glories will be annual plants, even in your mild climate. Annuals are defined as plants that grow, flower, and produce seed all in one season. It's a genetic thing. (Your pepper plant grows as a perennial in mild climates even though it's usually considered an annual by most gardeners.) Morning glories (Ipomoea tricolor) do not like to be moved once they've begun to grow, so be sure to sow the seeds directly in the ground, or in they pots they will inhabiting.
There are perennials in this same family. If you want the plants to reappear year after year you might want to grow Ipomoea acuminata (Blue Dawn Flower), or Ipomoea quamoclit (Cypress Vine/Cardinal Climber). Both these plants will thrive in full sunshine with very little water once established.
