Morning Glory Flowers

Type of Flower
Morning glory:
Morning glory is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are: Calystegia ,Convolvulus, Ipomoea, Merremia, Rivea, Astripomoea, Operculina, Stictocardia ,Argyreia and Lepistemon
Most morning glory flowers unravel into full bloom in the early morning. The flowers usually start to fade a few hours before the "petals" start showing visible curling. They prefer full solar exposure throughout the day, and mesic soils. Some morning glories, such as Ipomoea muricata, are night-blooming flowers.
In some places, such as Australian bushland, some species of morning glories develop thick roots and tend to grow in dense thickets. They can quickly spread by way of long, creeping stems. By crowding out, blanketing and smothering other plants, morning glory has turned into a serious invasive weed problem.
In cultivation, most are treated as perennial plants in frost-free areas and as annual plants in colder climates, but some species tolerate winter cold. There are some species which are strictly annual (e.g. I. nil), producing many seeds, and some perennial species (e.g. I. indica) which are propagated by cuttings. Some moonflowers, which flower at night, are also in the morning glory family. 
Because of their fast growth, twining habit, attractive flowers, and tolerance for poor, dry soils, some morning glories are excellent vines for creating summer shade on building walls when trellised, thus keeping the building cooler and reducing heating and cooling costs. 
Popular varieties in contemporary western cultivation include 'Sunspots', 'Heavenly Blue', the moonflower, the cypress vine, and the cardinal climber. The cypress vine is a hybrid, with the cardinal climber as one parent. 
Many morning glories will self-seed in the garden. They have a hard seed coat which delays germination until late spring, at which time they will grow and flower rapidly. To improve the germination of purchased seeds, soak them in a dish of warm water overnight before planting.
Morning glory was first known in China for its medicinal uses, due to the laxative properties of its seeds. It was introduced to the Japanese in the 9th century, and they were the first to cultivate it as an ornamental flower. During the Edo Period, it became very popular. The Japanese have led the world in developing varieties. Hundreds have evolved, such as a brownish coloured variant known as Dajuro, and varieties with such evocative names as 'Brocade of Dawn', 'Moon in the Dusk' and 'Wisteria Girl'. It has come to symbolize summer in Japanese horticulture and art.
Ancient Mesoamerican civilizations used the morning glory species Ipomoea alba to convert the latex from the Castilla elastica tree and also the guayule plant to produce bouncing rubber balls. The sulfur in the morning glory's juice served to vulcanize the rubber, a process predating Charles Goodyear's discovery by at least 3,000 years.Aztec priests in Mexico were also known to use the plant's hallucinogenic properties.
