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.

Double Amber vs. Other Calibrachoa Varieties

Superbells® Double Amber is one of the richest and most substantial selections within the double-flowered Superbells® Lineup, prized for both its warm coloration and dense, layered blooms. Compared to Double Twilight, which leans cooler and more dramatic with deeper, moodier tones, Double Amber reads brighter and more approachable, bringing warmth without heaviness. When set beside Doublette Love Swept, the contrast becomes one of saturation and intent—Double Amber delivers fuller, golden-amber color with more visual weight, while Love Swept favors a softer, romantic blush and a gentler overall presence. Against single-flowered warm varieties like Superbells® Coral Sun, Double Amber immediately distinguishes itself through texture, adding depth and dimension that only a true double bloom can provide.

When compared to Cha-Cha™Series, Double Amber feels more substantial and composed, with thicker petals and a less playful, more luxurious look. Cabaret® Selections—particularly in darker or refined tones—tend to emphasize control and polish, while Double Amber embraces abundance and fullness. Used alongside Colibri® Pure White, its warm amber tones become even more luminous, creating crisp contrast and visual clarity. Paired with Calitastic® Cappuccino, Double Amber forms a rich, coffee-and-cream color story that feels intentional, elevated, and designer-driven—ideal for containers that aim to feel warm, sophisticated, and visually indulgent rather than bright or trendy.
