Dahlia White Swan

Dahlia White Swan: A Pristine White Tuber for Sun-Kissed Blooms

Create a clean, elegant statement in your garden with the Dahlia White Swan tuber. This robust, upright plant grows to a height of 100–120 cm with a bushy spread of approximately 60 cm. Its sturdy, hollow stems carry snow-white, camellia-type blooms, 11–15 cm across, that keep their pristine colour even under strong sun. The centers may show a faint creamy glow when they first open, adding a subtle touch of warmth. This is an exceptional variety for moon-garden accents and all-white pastel borders.

Dahlia White Swan is a true workhorse for cut-flower enthusiasts. The blooms are held on long, straight stems and boast an impressive vase life of 7–10 days when harvested at the tight-bud to half-open stage. They are perfect for creating a clean, all-white statement in large patio pots and for producing abundant flowers for beautiful bouquets. With consistent dead-heading and maintenance, you can expect over 80 pristine flowers per plant throughout the long flowering season from late November through March.

Planting & Care Guide
