Description

Dahlia 'Double Extreme' is a very attractive collection of compact dahlias with semi-double or fully double blooms in a wide array of warm, intense shades. Planted en masse, they will be a great addition to any garden, no matter how small, as well as terraces or balconies. This selection is first year flowering, blooming prolifically from July until the first frosts. Ideal for borders, growing to the front of flowerbeds or in pots.

Dahlias belong to the Asteraceae family and are native to Mexico. Nowadays, some 20,000 horticultural varieties are grown in gardens all over the world. 'Double Extreme' produces dwarf plants with a bushy, compact habit, that don’t require support. Each plant grows to approximately 50 cm in height and 40 cm in width. The flowering period takes place from July to October. The 6 cm wide, semi-double or fully double corollas are made up of several rows of ray flowers in a variety of warm, sunset shades including white, yellow, orange, red and deep red, surrounding a yellow central disc. Blooms are plain or two-toned. The stems are well branched and hollow, bearing opposite leaves that are subdivided into 3 or 5 toothed lobes. Both leaves and stems are dark green. To encourage repeat flowering and extend the flowering period, take care to remove faded flowers regularly. Better still, cut the flowers regularly to create beautiful, colourful arrangements.

Dahlias are great for creating patches of colour towards the front of summer beds and borders. They combine well with Echinacea, Helenias and Cosmos or with the soft, feathery plumes of ornamental grasses such as Pennisetum villosum. This dwarf variety is particularly suitable for growing in pots and containers on the patio or balcony.

Planting and care

Sow in February-March, in seed trays or pots filled with sowing mix. Bury the seeds under 1.5 mm of fine soil. Place in a propagator or somewhere warm, at a temperature of 18 to 20°C. Germination takes 7 to 21 days. Transplant the seedlings into individual pots when they are strong enough to be handled, taking care not to damage the roots. Harden the plants off gradually and plant them out when all risk of frost is over, leaving 30 cm between each plant.

Dahlias enjoy full sun and rich, cool, well-drained soil. Stagnant humidity can cause the tubers to rot. If necessary, amend the soil with compost and sand. Dig over the plot thoroughly and enrich the soil with hoof and horn meal fertilizer. After planting, water once abundantly and repeat this regularly for the first 6 weeks to help root development.

Dahlias are sensitive to cold temperatures and must be overwintered indoors. In November, when the first frosts blacken the foliage, dig up the tubers carefully. Clean off as much soil as possible. Allow the foliage to dry, so that the tubers can rebuild their food reserves. Then cut the stems back to about 10 cm. Spread your bulbs in a crate on newspaper. Store them in a dry, cool, dark place, such as a garage or attic, sheltered from frost. In warmer climates, Dahlias can be left in place and protected under a layer of mulch (leaves, straw etc.)
