Morning glory

Morning glory is a common name for over 1,000 species of flowering plants in the family Convolvulaceae, Morning glory was first known in China for its medicinal uses, due to the laxative properties of its seeds.The seeds of many species of morning glory contain ergoline alkaloids such as the psychedelic ergonovine and ergine (LSA).

Most morning glory flowers unravel into full bloom in the early morning.  They prefer full solar exposure throughout the day, and mesic soils. Some morning glories, such as Ipomoea muricata, are night-blooming flowers.

Morning glory 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.
