Superbells® Lemon Slice® is one of the most iconic and recognizable Calibrachoa hybrids on the market. Developed by Proven Winners, it is famous for its unique "pinwheel" flower pattern, featuring crisp white petals with a vivid lemon-yellow star centered on each bloom. It maintains a tidy, mounded-trailing habit and is specifically bred for high flower count and improved garden vigor. Like others in the Superbells series, it is heat tolerant and stays covered in blooms from spring through the first frost without the need for manual deadheading.
Mature size: 6–12 inches in height with a spread of 12–24 inches.
Flower: Small, trumpet-shaped flowers with a distinct stable bicolor pattern of bright yellow and pure white stripes.
Foliage: Small, lance-shaped green leaves that stay compact and dense, providing a lush foundation for the high-contrast blooms.
Hardiness: Typically grown as an annual; perennial in USDA zones 9–11.
This plant performs best in full sun (6+ hours of direct sunlight). Plenty of light is necessary to maintain the intensity of the yellow "slices" in the flower pattern and to prevent the stems from becoming sparse or leggy.
Superbells Lemon Slice has moderate water needs but is very sensitive to overwatering. It is essential to ensure the top of the soil feels dry to the touch before watering again. For containers, ensure there are functional drainage holes to prevent water from pooling at the root zone.
Requires excellent drainage and a slightly acidic soil environment (pH 5.5–5.8). It is specifically designed for use in containers and hanging baskets; it rarely performs well when planted directly in heavy ground soil. Using a professional-grade potting mix is the best way to ensure the fast drainage these plants crave.
This is a heavy feeder. To keep the "Lemon Slice" pattern vibrant and the foliage a deep green, apply a water-soluble fertilizer every 1–2 weeks. Look for fertilizers containing chelated iron to prevent the leaves from turning yellow, which can happen if the soil pH rises.
The plant is self-cleaning, so spent flowers will drop off naturally without help. If the plant begins to look open or "tired" during the mid-summer heat, a light pruning—removing 1–3 inches from the trailing ends—will encourage branching and a fresh burst of flowers for the autumn.
Lemon Slice is a world-class "spiller" and "filler" for container recipes. Its bright, cheerful pattern pairs exceptionally well with blue, purple, or white companions. It is a standout choice for window boxes and hanging baskets where its unique pattern can be viewed at eye level. It is also a magnet for hummingbirds and other small pollinators.
Superbells® Lemon Slice® remains a garden favorite for its unmistakable "sunshine-in-a-pot" appearance. Its reliable performance, coupled with a truly unique bicolor bloom, makes it a must-have for any sunny patio or balcony display where high-contrast color is desired.
