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 Perfect'
Dahlia 'Hapet Perfect', also known as Dahlia 'Hapet P', is a variety that feels quietly confident, offering refined colour with a gentle sense of theatre. Its medium fimbriated blooms are wonderfully tactile, each petal finely fringed to create a soft, glowing texture. The colouring begins with a creamy yellow base, warm and luminous, before shading gradually towards lilac pink at the tips. In bright sunshine, Dahlia 'Hapet Perfect' seems to catch and reflect the light, giving the flowers an almost radiant quality that feels fresh rather than flashy. The interplay between cream and pink brings depth without heaviness, making this dahlia an elegant companion to both pastel and stronger planting schemes. There is a pleasing balance to Dahlia 'Hapet Perfect', where detail and colour work together to create a bloom that rewards closer inspection.
Flowering generously from summer into early autumn, Dahlia 'Hapet Perfect' offers consistency as well as beauty. Its neatly formed flowers are held on strong stems, making it a reliable presence in borders and an excellent choice for cutting. In a vase, Dahlia 'Hapet P' brings softness and light, pairing beautifully with airy foliage or deeper-toned companions. Despite its refined appearance, it is an easy-going plant, thriving in a sunny position with well-prepared soil. Whether grown as part of a mixed display or allowed to shine in its own space, Dahlia 'Hapet Perfect' delivers a season-long performance that feels polished, uplifting, and effortlessly charming.

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.
