Shock Wave® Rose Spreading Petunia

Shock Wave® Rose is a mounded, spreading petunia with rose-colored flowers and a compact 7–10-inch height. Its listed 20–30-inch spread supports use as a container spiller or as a spreading accent in sunny beds. ## Garden Use Use this cultivar in baskets, window boxes, mixed planters, and other small spaces where trailing growth can soften the edge. The exact [Shock Wave Rose page](https://www.panamseed.com/Products/048605220004669/spreading-petunia-shock-wave-rose/) lists spring through late-summer flowering, full sun, and 10–15-inch spacing. The series flowers in a short, coordinated window and its small blooms recover quickly after rain or overhead watering. ## Growing Conditions Give it full sun and fertile, well-drained soil. Keep the root zone evenly moist while it is growing, particularly in pots, but avoid persistent saturation. [RHS petunia guidance](https://www.rhs.org.uk/plants/166779/petunia-cascadias-yellow-eye-dancasye-cascadias-series/details) supports full sun and free-draining soil; [RHS container research](https://www.rhs.org.uk/science/gardening-in-a-changing-world/water-use-in-gardens/watering-containers) advises against overwatering. ## Maintenance Deadhead spent flowers as they fade and check containers regularly during hot, dry spells.
