Always one of gardeners' favourite annuals, petunias now come in newer varieties offering even more spectacular shows of colour than ever before. The Wave Petunia and Supertunia are among those available at nurseries in the spring.

The Wave

Wave petunia variety has become more and more popular since its introduction in the 1990s. It comes in three sizes: Tidal, the largest flower; Shock, the smaller flower; and Easy, a spreading plant.

Features of the Wave

Garden experts seem to agree that the Wave petunia was developed primarily as a ground cover. It may become overgrown in late summer and require pruning.

Wave propagation

The Wave petunia is propagated with seeds and tends to grow a huge root system. The root ball may be a problem in baskets and planters.

The Supertunia

The Supertunia is the most recent development in petunias. It too comes in many colours and sizes, as well as in single and double blossoms.

Supertunia features

The Supertunia variety adapts better to planting in pots than the Wave because it drapes easily over the sides and grows very large without developing the massive root system of the Wave.

Supertunia propagation

The Supertunia is propagated with cuttings, thus preserving its quality and vigour.
