More About Petunia ‘Supertunia® Royal Velvet’

Petunia ‘Supertunia® Royal Velvet’ is prized for its rich, saturated royal-purple blooms with a soft, velvety finish. The color is deep and luxurious, holding exceptionally well through summer heat without fading or washing out, even in full sun.

As part of the Supertunia® series, this variety is self-cleaning and continuously blooming, eliminating the need for deadheading while maintaining a full, well-branched habit. Flowers are produced steadily from late spring until frost.

Why We Like It (Our Trials)

In our trials, ‘Royal Velvet’ has been a reliable, season-long performer, combining strong flower production with excellent heat tolerance. It maintains clean foliage, consistent color, and an attractive shape with minimal maintenance.

We especially appreciate its design versatility. The deep purple pairs beautifully with yellows, whites, pinks, chartreuse foliage, and silver accents, making it easy to incorporate into both bold and elegant container designs.

Supertunia® Royal Velvet vs. Other Petunias

Royal Velvet stands out in the Supertunia® Series for delivering the deepest cool-toned purple without slipping into black. The color is rich and saturated, and even with its aggressive growth, flowering stays dense and uniform through heat. When set beside Supertunia® Bordeaux™, Royal Velvet reads cooler and more dramatic, trading wine warmth for regal depth. In contrast to Supertunia® Black Cherry, it gives up red undertones in favor of a more sophisticated, composed look. Viewed alongside Supertunia® Hoopla™ Vivid Orchid, Royal Velvet feels solid and restrained, prioritizing uniform color over graphic pattern.

Looking beyond the core Supertunias, Royal Velvet offers far more precision than the Supertunia Vista® Series, which emphasizes mass coverage and bold scale. Vista purples flood space quickly, while Royal Velvet provides depth without visual overload, making it easier to design with intention. Royal Velvet reads classic and refined, while varieties like Crazytunia® Black Mamba lean more heavily into novelty and near-black drama. Royal Velvet also spreads wider and maintains its color more reliably through stress, giving it a more polished and dependable presence over the season.
