Harris Seeds Petunia Tidal Wave Seed
Best low-maintenance choice for gardeners seeking resilient, fast-spreading landscape color.

While they lack the delicate, trailing elegance of traditional varieties, their shrub-like resilience and aggressive four-foot spread make them an unbeatable choice for filling large spaces with consistent, weather-proof color.
