This mixture of Dahlia Showpiece Mixed Hybrids brings together decorative dahlias with often very double flowers, like large pompoms in rich, bright and varied shades. Some of the varieties that make up this mix are among the most beautiful and have been awarded. Derived from seeds, these plants with an upright habit equal the varieties traditionally cultivated vegetatively and flower in the year of sowing. Floriferous and robust, they are perfect for borders or in bouquets.
Dahlias belong to the asteraceae family, they are originally from the high plateaus of Mexico. At present, the some 20,000 horticultural varieties obtained by humans have invaded, to our great pleasure, gardens all over the world.
The 'Showpiece Mixed Hybrids' variety is a decorative dahlia, it will reach 1 m (3.3 ft) in height, with a width of 50 cm (19.7 in). Plants from this selection often show very double flowers. For this reason, it can also be classified as a pompom dahlia: it is a horticultural category defined by the shape of the flower. In this group, the coloured ligules of the head are countless, forming a ball-shaped inflorescence. The flowers of this selection are 8 cm (3.1 in) in diameter, they are violet, red, lavender, yellow, carmine, pink or salmon, in an infinite gradient. The golden heart of the flower only appears late, just before wilting. The flowering period is from July to October. The habit is upright, it is sometimes necessary to stake the plants at the end of the season. The very branching stems are hollow and the leaves are opposite, pinnately divided into 3 or 5 very toothed lobes. The leaves and stems are purple.
To promote flowering again, make sure to remove faded flowers, or even better, regularly make large colourful bouquets by combining it with other varieties. In the back of the border, this Dahlia will form colourful spots in the company of Echinaceas for example, which bloom at the same time, as well as Daylilies or Asters. With Sedums and Miscanthus, it will also make a lovely original mix.
As a star plant for borders and herb gardens, Dahlias confidently accompany the most beautiful flowers but are also appreciated alongside vegetable plants. In Mexico, this tuberous plant was first cultivated as a root vegetable for consumption. But its poor taste qualities have relegated it to the rank of ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Botanical data
Sow in February-March, in trays or pots in a special seed compost that you place in a mini-greenhouse or in a warm place, to maintain a temperature of 18 to 20°C. The seeds will be buried under 1.5 mm (0.1 in) of fine compost. Germination will occur within 7 to 21 days. Transplant the young plants into 8 cm (3.1 in) pots when they are large enough to be transplanted, taking care not to damage the roots.
Gradually harden off these seedlings and transplant them when all risk of frost is gone, spacing them 30 cm (11.8 in) apart.
Plant Dahlias in full sun as soon as the last frost has passed, rich, fresh, and well-drained soils are perfect. However, stagnant moisture would promote tuber rot. Feel free to amend the soil with compost and sand if necessary. Work the soil deeply and enrich it, for example, with crushed horn or dehydrated blood. At the end of planting, water once abundantly and then regularly renew this watering during the first 6 weeks to help with rooting.
Dahlias are sensitive to cold, they need to be overwintered. In November, the first frost will blacken the foliage, it's time to dig them up. Carefully unearth the tubers. Remove as much soil as possible. Let the foliage dry, so that the tubers can replenish their reserves. Then cut the stems to 10 cm (3.9 in). Spread your bulbs in a box on newspaper. Store them protected from frost in a dry, cool, and dark place, such as a frost-free garage or an attic, for example. In southern regions, close to the coast, which experience only a few days of frost per year, it is possible to leave them in place. In this case, simply cover the ground with a layer of leaves or straw as protection.
This tall Dahlia, with its hollow stems, does not withstand wind or heavy rain well. To overcome this drawback, you can stake it, but let's admit it, it is not very aesthetic. On the other hand, by pinching the stems early or removing the axillary flower buds, you will spread out the habit of the plant, which will offer more resistance to bad weather. At the same time, you channel the flow of sap to a single flower, which will become larger and stronger.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
