Dahlia Blueberry Classic

Dahlia Blueberry Classic: A Collector’s Tuber with Two-Tone Blooms

Transform your garden into a showcase with the Dahlia Blueberry Classic, a highly sought-after tuber for its breathtaking two-tone flowers. This remarkable plant grows to a height of 110–120 cm with a spread of approximately 60 cm, featuring an upright, well-branched habit and sturdy stems. The fully-double blooms, measuring a generous 12–14 cm, are a true spectacle. Each flower is coloured with twilight-mauve on the upper petals and a rich blackberry-purple on the reverse, creating a unique two-tone shimmer that changes beautifully with the light.

Dahlia Blueberry Classic is a limited-availability tuber, making it a favourite among collectors. Its strong stems and premium blooms are perfect for creating sophisticated cut flower arrangements with a vase life of 7–10 days. The plant flowers generously from early December through March, providing a continuous display of colour. With proper care, consistent deadheading can yield over 100 flowers per plant throughout the season.
