Ipomoea acuminata, or Ipomoea indica var. accuminata, is more commonly known as the blue dawn flower or oceanblue morning glory. It is a twining vine common to the southern United States. The plant grows rapidly and is known for climbing and presenting hundreds of beautiful blue flowers that open first thing in the morning.
The vines of the oceanblue morning glory are tender and bright green when new, and they turn reddish green as they mature. The leaves are ivy-shaped with three distinct lobes. The vivid blue flowers are funnel-shaped and flare dramatically to a slightly rounded pentagon with frilled edges. A starlike pattern is often visible in the petals of the flower.
Morning glory plants are fast-growing seasonal perennials. They are a warm-weather plant, growing best in hardiness zones 8 through 10. Morning glory vines can easily cover fences, walls, pergolas and other supporting structures. The plant puts on a showy display of flowers that range from whitish-blue to deep blue in color. The flowers close as the day ends.
Morning glory vines can reach lengths of 25 feet in one season. They tend to grow in large mats of multiple intertwined stems lined with large, singular, dark-green leaves and many flowers. Seed heads produced by the plant are small and podlike and hold several brown or black seeds that are disbursed when the head splits open.
The plant prefers full sun and requires a lot of watering to thrive. Morning glory plants are easy to grow and tolerate a range of soils as long as they are not too heavy and drain well. Pruning is generally not required, although the plant can be trimmed to control excessive growth. The plant is most easily propagated from seeds.
Morning glory is used as an ornamental that is trained to grow over trellises and latticework and is frequently used to cover unsightly items, such as chain-link fences. Morning glory also makes a good single-season ground cover. It can help to reduce erosion on exposed banks and slopes, while other woody plants and perennials fill in.
