Appearance and growth

The flowers of Ipomoea violacea have a trumpet-like shape and various colors, including white, red, purple and blue. The leaves are heart-shaped, with the nearly equal length and width of 8–16 cm. They are attached by a thin, about 10 cm long petiole

The condition of trance induced by drinking the infusion was used by local shamans to communicate with spirits "for the purpose of divination and diagnosis". The Spanish colonizers of Mexico suppressed this practice, but it was continued in the mountainous regions.
