More About Calibrachoa ‘Superbells® Coral Sun’

Calibrachoa ‘Superbells® Coral Sun’ delivers a cheerful, sun-kissed color palette with soft coral blooms warmed by golden-yellow centers. The color reads bright without being overpowering, making it easy to blend into a wide range of container and garden designs.

As part of the award-winning Superbells® series, this variety is bred for vigorous growth, excellent branching, and reliable season-long flowering. ‘Coral Sun’ maintains strong color saturation and dense bloom coverage even during intense summer heat.

Why We Like It (Our Trials)

In our trials, ‘Superbells® Coral Sun’ has been an exceptionally dependable performer in full-sun containers and hanging baskets. It establishes quickly, trails evenly, and continues blooming heavily with consistent feeding throughout the season.

We especially like its design flexibility. The warm coral tones pair beautifully with whites, yellows, purples, blues, and chartreuse foliage, making it a versatile filler or spiller in mixed containers. Flowers are self-cleaning, keeping maintenance minimal.

Coral Sun vs. Other Calibrachoa

Superbells® Coral Sun is one of the warmest and most inviting selections in the Superbells® Series, landing squarely between soft coral and orange without drifting into harsh or neon territory. When compared to Superbells® Tangerine Punch, Coral Sun feels more refined and evenly balanced, while Tangerine Punch leans harder into vivid, citrus-driven brightness. Set beside Watermelon Punch, Coral Sun trades high contrast for cohesion in a blended, sunset-inspired palette that feels more natural and fluid. Compared to Superbells® Pomegranate Punch, Coral Sun is lighter and more summery, while Pomegranate Punch carries deeper red tones and a richer, more dramatic presence.

When placed outside the Superbells® family, Coral Sun continues to distinguish itself through fullness and seasonal performance. Compared to Cha-Cha™ Varieties, it presents a slightly bolder flower face and a more vigorous overall habit, giving containers a fuller look with less effort. When paired with Calitastic® Cappuccino, Coral Sun truly shines—its warm coral tones breathe life into Cappuccino’s smoky, muted color palette without overpowering it. The result is a combination that feels intentional and upscale, delivering warmth and energy while maintaining a polished, designer-level aesthetic.
