The Ultimate White Dinnerplate Dahlia

Pre-order for dispatch end of February 2026.

The Dahlia 'White Perfection' lives up to its name in every way. This spectacular "dinnerplate" variety produces enormous, fully double blooms that can span over 20cm across. The petals are a pristine, snowy white, arranged in glorious ruffled layers that create a cloud-like effect in the garden. It is the gold standard for white dahlias, offering unmatched size and purity.

Standing tall at the back of the border, 'White Perfection' commands attention. It is a firm favourite for summer weddings and luxury floristry, where its giant flower heads are used to create breathtaking bridal bouquets and centerpieces. Despite its delicate appearance, it is a vigorous grower with lush green foliage that provides the perfect backdrop for its luminous blooms.

GROWING TIP

Like all dinnerplate dahlias, the flower heads are heavy. Staking is non-negotiable—insert a strong cane when planting the tuber to support the stems against wind and rain. For show-stopping giant blooms, remove the side buds (disbudding) to channel all the plant's energy into the main flower.
