Morning Glories are an annual vine with ovate, deeply cordate leaves 3-4 inches long and 3/4-3 inches wide.

The trumpet-shaped Morning Glory flowers vary from white to red, purple, blue, or violet-blue. The ovoid fruit is about 1/2 inch in length and bears elongate, angular black seeds.

The seeds of several varieties of Morning Glory (Ipomoea violacea) contain a naturally occurring indole called Lysergic Acid Amide (LSA). Due to their psychoactive properties the seeds were used ritually by Aztecs.
