The iridescent pink blooms of 'Opera Supreme Pink Morn' petunia are most striking--because, says AAS, "a silvery shine causes the blooms to shimmer." The flowers are 2-1/2 inches wide and pink with a white center and yellow throat. (The three colors make it a "morn" variety.) The plant grows 4-6-inches high and 3 feet long. As a trailing petunia, it's excellent in containers or hanging baskets and also thrives in the garden, where, says AAS, it actually chokes out weeds.
