This Costco value pack includes 10 Wave Petunia plants, each grown in a 4-inch (414ml) pot and ready to transplant into your garden, containers, or hanging baskets. Wave Petunias are a premium annual flowering plant prized for their vigorous, spreading growth habit and season-long color from spring through first frost.

Wave Petunias grow just 5 to 7 inches tall but spread 2 to 4 feet wide, making them excellent for ground covers, container arrangements, and cascading from hanging baskets. Unlike standard petunias, Wave varieties do not require deadheading to maintain continuous blooming — they naturally set new buds from both the center and ends of their stems. They also demonstrate excellent recovery after rain and good tolerance to both warm and cool temperatures.

For best results, plant in a location that receives at least 6 hours of direct sunlight per day in well-draining, moderately fertile soil. Water containers regularly, as potted plants dry out faster than in-ground plantings. Feed every 10 to 14 days with a liquid fertilizer to support the vigorous spreading growth and sustained blooming throughout the season.
