Dahlias are half hardy, so keep them protected from frost. Pot tubers individually between February and April and grow them on in a greenhouse or bright indoor position. Alternatively, start them outside in May, once the risk of frost has passed.
'Hapet Blue Eyes'
Dahlia 'Hapet Blue Eyes' is unapologetically glamorous, delivering the kind of flower that stops gardeners mid-step. This magnificent Dinner Plate dahlia produces vast, beautifully proportioned blooms reaching up to 25cm across, each one a study in elegance and restraint. The petals open in creamy white, their edges gently brushed with lilac-purple, as though tinted by twilight. This subtle shading gives the flowers depth and softness, preventing the scale from ever feeling overwhelming. In full bloom, Dahlia 'Hapet Blue Eyes' feels luxurious rather than loud, combining presence with poise. The flowers sit confidently atop tall, strong stems, rising above the foliage to command attention in borders, patio pots, and generous containers alike. Whether viewed up close or from across the garden, Dahlia 'Hapet Blue Eyes' delivers drama with a refined, almost painterly touch.
Flowering from midsummer until the first frosts, Dahlia 'Hapet Blue Eyes' offers a long season of impact just when the garden is at its most expressive. Its height and generous blooms make it exceptional for cutting, where a single stem can anchor an entire arrangement with ease. Indoors, the softly shaded petals catch the light beautifully, pairing well with both bold companions and simple greenery. Despite its impressive scale, Dahlia 'Hapet Blue Eyes' is surprisingly versatile, suiting contemporary planting schemes as readily as more traditional displays. For gardeners seeking a show-stopping dahlia that balances grandeur with grace, Dahlia 'Hapet Blue Eyes' is an unforgettable choice.

Plant calendar
For planting out later, use a snug-fitting 15–20cm pot filled with peat-free multipurpose compost. For a patio display, plant directly into a container at least 30cm wide and keep it somewhere bright and frost free until it can move outdoors.
Position the old stem facing upwards, with the tubers covered and the stem stump level with the compost. Tubers naturally vary in size and shape and may arrive without visible buds. Bent necks are usually fine if they remain firmly attached, so do not remove them.
Water after planting, then allow the compost to become almost dry before watering again while the tuber remains dormant. Once shoots and leaves are growing strongly, water more regularly, always allowing excess water to drain away.
Plant out after the last frost, once the plant is around 20–30cm tall and its roots hold the compost together. Space dahlias approximately 30–50cm apart in borders, allowing less room for compact varieties. Water thoroughly after planting.
Water regularly during active growth and deadhead or cut flowers often. Dahlias usually bloom from July or August until the first frost, although later-planted tubers may start in late August or September. In autumn, lift, clean and dry the tubers, then store them somewhere cool, dry, airy and frost free.
