Opera Supreme petunias were bred for the mounded, yet low-growing plant habit that is covered with a profusion of blooms that literally encase the plant, from center to tip. The trailing habit makes it versatile enough for a number of uses such as hanging baskets, window boxes and planters, mixed containers, and 4" production for garden beds. Opera Supreme petunias demonstrate less day-length sensitivity than some other series on the market, causing it to flower earlier in the production cycle.
