It is most commonly called "beach moonflower" or "sea moonflower" as the blooms, white in colour, open at night.
Most of the plants cultivated under this name, including the popular cultivar 'Heavenly Blue' and the plants used as a hallucinogen, actually belong to the related species Ipomoea tricolor. The true I. violacea is rarely seen in cultivation.
