More About Petunia ‘Supertunia® Really Red’

Petunia ‘Supertunia® Really Red’ is prized for its clear, true red flowers, a color that holds exceptionally well without fading or turning pink in summer heat. The blooms are produced continuously and remain vibrant from spring through fall, making this one of the most dependable red petunias available.

As part of the Supertunia® series, this variety is self-cleaning and vigorously branched, eliminating the need for deadheading while maintaining a full, attractive habit.

Why We Like It (Our Trials)

In our trials, ‘Really Red’ has been a consistent top performer, especially in hot, sunny conditions where other red petunias can struggle. It maintains strong color saturation, flowers heavily, and keeps a balanced shape with minimal maintenance.

We especially appreciate its design reliability. True red is notoriously difficult to maintain in the garden, and ‘Really Red’ delivers season-long intensity that works beautifully as a focal plant or bold accent.

Supertunia® Really Red vs. Other Petunias

Really Red stands out as the cleanest, most classic red available in the Supertunia® Series. It grows quickly with a spreading habit, delivering instant impact and maintaining nonstop bloom even through peak summer heat. When lined up with Supertunia® Black Cherry, Really Red reads brighter and more energetic, commanding attention without the need for pattern or novelty. Set alongside Supertunia® Saffron Finch, it functions as a contrast color rather than a source of warmth. Its power comes from clarity and simplicity, especially when viewed next to the more graphic Supertunia® Hoopla™ Vivid Orchid.

In relation to Crazytunias®, Really Red is built for performance rather than decoration. Crazytunias emphasize pattern and personality, while Really Red excels through consistency, speed, and durability. It establishes faster and maintains color longer across the season. Compared to the Supertunia Vista® Series, Really Red offers greater control and flexibility. The closest Vista equivalent to Really Red is Supertunia Vista® Fuchsia, which fills the same role as a high-impact, visually dominant color but at a much larger, landscape-scale size. Really Red adapts easily to both containers and landscape beds, making it a strong choice when bold contrast and dependable performance are the priority.
