More About Calibrachoa ‘Superbells® Lemon Slice’

Calibrachoa ‘Superbells® Lemon Slice’ is one of the most recognizable and eye-catching calibrachoa varieties available, prized for its bright lemon-yellow blooms accented with a crisp white star pattern. The bold contrast creates instant visual interest and makes this variety stand out even from a distance.

As part of the award-winning Superbells® series, ‘Lemon Slice’ delivers vigorous growth, excellent branching, and nonstop flowering. The plant quickly fills containers and baskets, maintaining strong bloom coverage from early spring through frost without fading or thinning.

Why We Like It (Our Trials)

In our trials, ‘Superbells® Lemon Slice’ has been an exceptionally strong performer in full-sun containers and hanging baskets. It establishes quickly, trails evenly, and continues blooming heavily through summer heat with regular feeding.

We especially like its design impact. The bright yellow-and-white pattern pairs beautifully with blues, purples, whites, and deep greens, making it an excellent focal plant in mixed containers. Flowers are self-cleaning, keeping maintenance minimal all season long.

Lemon Slice vs. Other Calibrachoa Varieties

Superbells® Lemon Slice is the most graphic and pattern-driven selection in the Superbells® Series, relying on bold contrast rather than depth of color for its impact. Compared to warm-toned varieties like Coral Sun or Tangerine Punch, Superbells® Lemon Slice feels noticeably cooler and more structured, replacing warmth with crisp definition. When placed beside Superbells® Watermelon Punch, it trades Watermelon’s soft, blended tones for sharp pattern and visual clarity. Compared to double-flowered options like Superbells® Double Amber, Lemon Slice sacrifices fullness and texture in favor of clean lines and immediate visual punch.

Outside the Superbells® family, Lemon Slice continues to stand apart. Compared to Cha-Cha™ Tangerine it reads more intentional and composed, with less playful movement and more deliberate design impact. Other Calibrachoa like our Cabaret® Selections rarely push contrast to this degree, which allows Lemon Slice to occupy a unique niche within mixed containers. Paired with Colibri® Pure White, its pattern becomes ultra-clean and architectural. Set next to Caliloco Dracula, Lemon Slice feels bold in an entirely different way—less theatrical and moody, and more graphic, modern, and sharply defined.
