About Ipomoea violacea L.
The corolla of Ipomoea violacea flowers is white. This white corolla distinguishes Ipomoea violacea from Ipomoea tricolor, which is commonly known as Heavenly Blue. Ipomoea violacea is sometimes mistaken for the cultivar Pearly Gates, which also has a white corolla. This misidentification likely occurs because of the species' misleading Latin binomial name: 'violacea' means purple.
