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
'Mediterrannee'
Dahlia 'Mediterrannee' brings welcome cool colour to high summer, looking fresh and vigorous just as other plants may be starting to flag. This decorative dahlia has those fabulous dinner-plate blooms that demand to be noticed. Boasting an exquisitely cool colour palette, with soft lavender flushed petals blending into elegant white, and with a contrasting deeper violet centre, this Dahlia will bring an air of sophistication to any planting scheme or bouquet. The large, attractive blooms of Dahlia 'Mediterrannee' are held upright on tall, sturdy stems, and make a superb cut flower.
Plant Dahlia 'Mediterrannee' in borders, it works well as a stand-alone plant, being big, bushy and up to 1.2m tall, but is equally suited to combining with other plants to add interest and drama to the garden through the summer months and into autumn. The cool pastel colours of Dahlia 'Mediterrannee' would work wonderfully with other soft and delicate shades, particularly pinks, whites and violets. Graceful ornamental grasses like Pennisetum would soften the mood even further.

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.
