Petunia integrifolia (syn. Petunia violacea), the violet petunia[3] or violetflower petunia,[4] is a species of wild petunia with violet-colored blooms.[5][6] Petunia integrifolia is native to Argentina.[7] P. integrifolia bears flowers approximately 1.5 inch in diameter and the plant is typically smaller and harder to cultivate than the well-known hybrid bedding Petunia now known correctly as Petunia × atkinsiana.[8][9]
The species was first described as Salpiglossis integrifolia by William Jackson Hooker in 1831.[10] It was transferred to the genus Petunia as P. integrifolia by Hans Schinz and Albert Thellung in 1915.[11] Petunia inflata had sometimes been considered to be a subspecies of P. integrifolia, but the two have different native ranges, with P. inflata growing in more northern areas.[12]
Petunia violacea Lindl. has been reported to be used as a hallucinogen in Ecuador, where the plant has the vernacular name shanín. The drug is said to cause sensations of levitation and flight - a type of hallucination often associated with the use of the more toxic hallucinogenic plants of the deliriant type; e.g., the tropane-containing Atropa and Hyoscyamus, active constituents of the witches' flying ointments of Medieval and Early Modern Europe.[13] [14]
