Morning glory (also written as 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'' * ''Lepistemon'' == Habit == 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Morning glory」の詳細全文を読む スポンサード リンク
