'Wave Purple' Petunia created a sensation in 1992 for its habit, unique for a petunia, of growing not vertically but trailing along the soil like an ivy, with stems that took root. Famed also for its vigor and disease resistance, the plant grows to 4-6 inches tall with a spread of 3-4 feet. Its impact on the gardening world made it an AAS Winner and also brought its breeder, Daigaku Takeshita, the All-America Selections Breeder's Cup Trophy.
