Simply put, wave petunias and Supertunias are both vigorous growers. But Supertunias will outperform wave petunias with their hardiness, resistance to diseases, and plant fullness. Additionally, Supertunias will have many more colors to choose from.

Both can be planted as groundcovers or borders or in pots and hanging baskets.

Wave petunias are aggressive ground covering annuals that can be grown from seed —often making these plants the more affordable option. Due to their spreading nature, wave petunias grow great in flower beds and gardens; they can also grow well in pots or hanging baskets.

Supertunias, on the other hand, can be thought of as an “elite” version of wave petunias. Supertunias were bred to bloom profusely, self-deadhead, and will spread similar to a wave petunia.
