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.

Dahlia
'Jowey Fantasy'
Four colours, countless combinations. Dahlia 'Jowey Fantasy' has a wonderfully imaginative approach to colour, blending creamy white, sunshine yellow, glowing orange and vivid red in flowers that seem to change with every glance. Each petal begins in warm yellow, develops rich red or orange markings and finishes with a delicate white tip. The result is a beautifully intricate pattern, with no two blooms looking quite alike. Some flowers are predominantly creamy yellow with soft peach accents, while others display bold flashes of scarlet. The tightly overlapping petals create rounded, almost ball-shaped blooms measuring approximately 10–12cm across. Bred in Belgium, Dahlia 'Jowey Fantasy' brings a lively mixture of colour and character to the summer garden.
Those fascinating flowers make Dahlia 'Jowey Fantasy' particularly appealing for cutting, with strong, straight stems that hold the blooms beautifully in arrangements. Pair it with creamy dahlias, purple salvias or airy ornamental grasses, or let its changing colours take centre stage in a sunny border. Growing to around 80–100cm, Dahlia 'Jowey Fantasy' appreciates fertile, well-drained soil and a sheltered position, with support if needed. Water during dry spells and pick or deadhead regularly to encourage fresh flowers until the first autumn frosts. Start tubers under cover in spring or plant outside once frost has passed, lifting them for frost-free winter storage in colder UK gardens. With Dahlia 'Jowey Fantasy', the next flower is always a little surprise.

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.
