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.
