A genus made up mainly of climbing plants.


The genus Ipomoea includes a few wild plants and numerous beautifully colored garden species. The garden morning-glory is one of the best known plants in this group. Others are the bindweed, jalap, moonflower, scammony, and sweet potato. It is native to North America, Asia, South Africa and the West Indies.

The morning-glory grows rapidly and twines about nearby objects. It grows from 10 to 20 feet high and is widely used as a covering for posts, fences, and porches. Cultivated plants have heart-shaped leaves and a profusion of trumpet-shaped flowers that usually close at noon. The leaves are green or variegated silvery-white in color. Flowers may be pink, rose, red, white or blue, and 4 to 5 inches across.

Morning-glories will grow in regular soil, which is moist to on the dry side, in a sunny location.

The most beautiful morning-glories were developed in Japan. As early as 1830 the cultivation of these plants, sometimes called Imperials or Emperors, was a popular hobby among the Japanese. Beautiful or rare plants were purchased at fantastic prices, and a single rare seed often sold for $25 or more. Constant hybridization caused a development of numerous new species with unusual flowers and leaves. Morning-glories were introduced into the United States in 1895.

The morning-glory is the flower for September.
