Morning glory

Most morning glory flowers curl up and close during the warm parts of the day, and are wide open in the morning, like their name. On a cloudy day, the flower may last until night. The flowers usually start to fade a few hours before the petals start curling. They prefer full sun throughout the day. Some morning glories - such as Ipomoea muricata - are night-blooming flowers.

Ipomoea aquatica (known as "water spinach", "water morning-glory", "water convolvulus", "Ong-Choy", "Kang-kung", or "swamp cabbage") is used as a green vegetable.
