More About Calibrachoa ‘Superbells® Double Amber’

Calibrachoa ‘Superbells® Double Amber’ stands out for its fully double, rose-like blooms in rich amber and golden-orange tones. The layered petals give the flowers a fuller, more luxurious look compared to single calibrachoa varieties, adding texture and visual weight to containers and baskets.

As part of the trusted Superbells® series, this variety delivers strong vigor, excellent branching, and consistent flowering. Despite its double blooms, ‘Double Amber’ flowers heavily and continuously from spring through frost without sacrificing performance or requiring extra care.

Why We Like It (Our Trials)

In our trials, ‘Superbells® Double Amber’ has been an excellent performer in full-sun containers. It establishes quickly, trails evenly, and maintains dense bloom coverage through heat and humidity with regular feeding.

We especially like its design impact. The warm amber tones pair beautifully with purples, blues, whites, and deep greens, making it a standout spiller in mixed containers. Flowers are self-cleaning, so the plant stays attractive without deadheading.

Calibrachoa ‘Superbells® Double Amber’ vs. Other Calibrachoa

Compared to single-flowered calibrachoa, ‘Superbells® Double Amber’ offers a fuller, more textured bloom that feels closer to a miniature double petunia—without the maintenance issues petunias can have.

When compared to standard petunias, calibrachoa provides smaller blooms but far heavier flower density and better heat and rain tolerance. For gardeners looking for a richly colored, double-flowered trailing plant with proven reliability, Calibrachoa ‘Superbells® Double Amber’ is an outstanding choice.
