Wave Petunia (Petunia x hybrida) is a fast-growing, spreading annual flower prized for its long bloom season and vibrant color range. This flat includes 18 ready-to-plant petunias in 2-gallon (7.5L) containers, ideal for filling flower beds, borders, hanging baskets, and mixed containers with cascading color from spring through fall.

Wave Petunias require full sun, needing at least six hours of direct sunlight daily for maximum flower production. They prefer moist, well-drained, slightly acidic soil (pH 5.5–6.3) and benefit from consistent watering and regular fertilizing due to their vigorous growth habit. Plants spread 2–3 feet wide and stay low to the ground, creating a lush, trailing effect. Available in a wide range of colors including pink, purple, rose, blue, lavender, and mixed varieties.

Plant outdoors only after the last frost, when soil temperature has reached at least 60°F. Deadheading spent blooms encourages continued flowering throughout the season.
