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.

Calibrachoa ‘Superbells® Lemon Slice’ vs. Other Calibrachoa

Compared to solid yellow calibrachoa varieties, ‘Lemon Slice’ offers a much bolder, patterned look that draws attention immediately. While single-color yellows brighten containers, this variety adds both color and graphic interest.

When compared to petunias, calibrachoa provides smaller blooms but far heavier flower density and superior heat and rain tolerance. For gardeners looking for a high-contrast, nonstop-blooming trailing plant, Calibrachoa ‘Superbells® Lemon Slice’ is one of the most popular and proven choices available.
