Rainbow Silence Cactus Dahlia Has Moved On — Shop Dahlias at Coast Farms
Dahlia ‘Rainbow Silence’ is a striking cactus-style dahlia known for its vibrant, multi-toned blooms blending shades of pink, coral, red, and golden yellow. Its uniquely shaped, pointed petals create a spidery, textured look, while the colours often shift and deepen as the flowers mature, giving each bloom a dynamic, “rainbow” effect.
Blooming from mid-summer until the first frost, this tall, bushy plant (typically 3–4 feet) produces abundant flowers that are perfect for garden borders, pollinator-friendly plantings, and cut flower arrangements.
This variety is no longer available on our website. If you're looking for vibrant, summer-blooming dahlias with bold colour and reliable performance, we invite you to explore the Coast Farms collection.
