Morning glory vines

There's something magical about morning glories, which do indeed bloom gloriously in the morning, then swirl closed as the day fades.

For growers Sheryl and Marshall Lozier, that's just what makes these vining annuals and perennials so irresistible. As you see in the photo above, perennial blue dawn flower (Ipomoea indica) scrambles up the side of their cottage. Elsewhere, another five-year-old plant weaves through a white-flowered potato vine (Solanum jasminoides) to cover a stucco arch.

"It's not for every garden," Sheryl says of the blue dawn flower. "It'll come in your doors and windows if you let it." To keep the vines in check, the Loziers prune them to 3 feet tall each January.
