More About Calibrachoa ‘Superbells® Watermelon Punch’

Calibrachoa ‘Superbells® Watermelon Punch’ is one of the most recognizable and playful Million Bells varieties available, featuring vivid watermelon-pink petals contrasted by bright lime-green centers. The bold color combination creates instant visual impact and remains vibrant even in intense summer sun.

As part of the award-winning Superbells® series, this variety is bred for vigorous growth, excellent branching, and nonstop flowering. ‘Watermelon Punch’ quickly fills containers and baskets with dense blooms, maintaining a balanced trailing habit from early spring through frost.

Why We Like It (Our Trials)

In our trials, ‘Superbells® Watermelon Punch’ has been an exceptionally reliable performer in full-sun containers and hanging baskets. It establishes quickly, trails evenly, and continues blooming heavily through heat and humidity with consistent feeding.

We especially like its design versatility. The pink-and-green color pairing works beautifully with whites, yellows, purples, blues, and chartreuse foliage, making it a standout focal plant or energetic accent in mixed containers. Flowers are self-cleaning, so maintenance stays minimal all season long.

Watermelon Punch vs. Other Calibrachoa Varieties

Superbells® Watermelon Punch is one of the most instantly recognizable selections in the Superbells® Lineup, prized for its bright pink blooms and lively contrast. Compared to Pomegranate Punch, Watermelon Punch reads lighter and more upbeat, trading depth and richness for a fresher, more cheerful appearance. When set beside Superbells® Coral Sun, it introduces sharper contrast and a stronger sense of definition, while Coral Sun remains smoother and more blended. Compared to Superbells® Grape Punch, Watermelon Punch feels warmer and more playful, leaning into pink tones rather than cooler purples.

Outside the Superbells® family, Watermelon Punch maintains its approachable, energetic personality. Compared to Cha-Cha™ Fuchsia, it feels softer and less intense, offering color that pops without overwhelming a container. Cabaret® Varieties tend to emphasize more refinement and structural control, while Watermelon Punch prioritizes fun, movement, and seasonal energy. When paired with Colibri® Pure White, its pink tones become crisp and highly vibrant, creating a clean, high-contrast look. Placed next to Caliloco Dracula, Watermelon Punch reads as more mainstream and friendly—less dramatic or edgy, but exceptionally easy to design with and broadly appealing.
