Shock Wave Spark Mix Petunia Seeds

The Original Wave Petunias transformed the way American gardeners grew petunias. Once a bedding plant, suddenly these new spreading types made every hanging basket and window box awash with bold color that just kept coming and coming. Well, there is an even better Wavethe Shock Wave series of earlier, more weather resistant, self-cleaning blooms. And Spark Mix is one of its most brilliant combinations, offering flower-child shades of pink, purple, blue, and cream for months on end.

Shock Waves start blooming much sooner in spring, thanks to less day-length sensitivity, and they keep coming all summer and into fall. And the old blooms obligingly drop from the plants, so no more deadheading for you. The 3 colors in this mixCoconut, Denim, and Pink Shadesall open at the same time, so you can enjoy a tricolored mix for months.

These trumpet-shaped 1- to 2-inch blooms simply blanket the plant beginning in mid-spring, weeks before other spreading petunias are even setting buds. Reaching 7 to 10 inches high with a very full, mounding shade, these plants spread 20 to 30 inches wide, and keep setting new buds in the center of the plant instead of just at the end of the stems. This way, Shock Wave looks as full and fresh in August as it did in May.

And the Shock Waves stand up to rain, humidity, heat, and other environmental stresses better than older Waves, bouncing back from summer showers and thunderstorms very well. Compact and very well-branched, they keep their lush, full habit.

Now, the one thing Shock Wave needs for its powerhouse blooms is food, so fertilize this plant a bit more heavily than you normally would to keep those flowers coming. Then settle back and enjoy.

This seed comes as a “pellet”. “Pelleted” seeds are small seeds that have been clay-coated to make them larger and more uniform in size and shape, making them easier to handle when planting.
