Morning glory flowers (Ipomoea purpurea or Convolvulus purpureus) are a common sight in many landscapes and may be found in any number of species within the Calystegia, Convolvulus, Ipomoea, Merremia and Rivea genera. While some varieties are described as noxious weed in some areas, the fast-growing vining plants can also make lovely additions to the garden if kept in check. All morning glory plants produce attractive funnel-shaped blossoms of various shades like white, red, blue, purple and yellow with heart-shaped leaves. Blooming usually occurs anywhere from May through September, opening in the morning and closing in the afternoon. Most types are annual, though in some warmer regions they will come back yearly or may re-seed themselves in almost any zone they grow in.
