E3 Easy Wave® Red White and Blue Mixture Spreading Petunia

E3 Easy Wave® Red White and Blue Mixture is a named spreading petunia for sunny seasonal color in containers, baskets, and garden edges. This is the named three-color mixture, bringing red, white, and blue flowers together while retaining the spreading E3 habit. ## In the garden PanAmerican Seed describes E3 Easy Wave plants as mounded and spreading, with a long flowering period and a manageable, uniform structure. The breeder lists an approximate mature height of 6–12 inches and spread of 25–32 inches, so allow room for the plant to extend beyond the pot or bed edge. Flowers are listed from spring through late summer, and the series is suited to baskets and planters. Illinois Extension recommends full sun and moist, well-drained soil for petunias. ## Planting and care Site in direct sun and use a free-draining container mix or garden soil. Water at the root zone when the surface begins to dry, then allow excess water to drain; containers need more frequent checks in warm weather. The RHS study of petunias in containers found that careful irrigation supported good plant quality, while overwatering reduced it. Keep the wide spreading habit in mind when spacing plants with companions so foliage and blooms have room to extend. ## Maintenance Remove faded flowers when a tidy display is desired, and trim damaged or overextended stems to keep the plant balanced. Check moisture regularly during hot, bright weather and adjust for rainfall; refresh the seasonal planting when flowering declines at the end of its growing period.
