Morning Glory; Heavenly Blue Morning Glory; Tlilitzin; Badoh Negro (seeds)
Ipomoea violacea is a common ornamental vine with heart-shaped leaves and bright white, pink, or purple flowers and small, black seeds that contain LSA. Because of its fast growth and prodigious seed production, many jurisdictions consider it an invasive weed plant. It has a long history of use in Central to Southern Mexico.
