The Petunia Supertunia series is known for its vigorous growth and abundant, vibrant blooms that cascade beautifully, making it perfect for garden beds, borders, and hanging baskets. An interesting characteristic of Supertunia petunias is their self-cleaning habit, meaning they don’t require deadheading to stay full and blooming, offering easy, low-maintenance color all season long.
In southern Louisiana, Supertunia petunias typically reach a height of 6 to 12 inches with a trailing spread of 18 to 24 inches, creating lush, flowing displays. They thrive in full sun, needing at least 6 hours of sunlight each day for continuous blooms. These petunias prefer well-drained soil and regular watering, keeping the soil consistently moist but not waterlogged for optimal growth.
