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.

Morning Glories ranged originally from mexico through tropical South America. If we are to judge from many ancient writers, morning glory seeds must have been very extensively used in the valleys of Mexico in pre-Hispanic times. It seems to have been more important in divinity than peyotl (Peyote) or teonanácatl (cubensis mushrooms).

Generations of Aztecs used the Morning Glory seeds to communicate with the Sun Gods and as a ritual hallucinogen. Natives in Mexico (Oaxaca region) believe that the deity lives within the seeds. In times of trouble they would eat the Morning Glory seed to gain knowledge from the deity.
