Description
The Décoratif Deuil du Roi Albert Dahlia, with its somewhat outdated name, is an old variety that does not leave anyone indifferent. Its large flowers are double, formed by numerous purplish-violet ligules more or less pointed with white, each flower has a different distribution of colours. This variety, of beautiful stature, always highly appreciated in our European gardens, remains nonetheless a very floriferous plant, which stands out in the background of a border. Also superb in bouquets.
Dahlias belong to the large family of Asteraceae, originally from the high plateaus of Mexico. Currently, the approximately 25,000 horticultural varieties obtained by humans have invaded, to our great pleasure, gardens around the world. Varieties of Dahlias are classified according to the shape of their heads. 'Deuil du Roi Albert', introduced in Belgium around 1934 and then reintroduced to the market in 2002 by the National Collection of the United Kingdom, is a Dahlia from the decorative group with large flowers. The inflorescences are composed of several rows of outer ligules that are almost flat, long and flexible, slightly incurved and curved towards the stem. The heads are opulent and measure up to 15 cm (6in) in diameter. Each ligule is wine red at the base, extends into a more purplish hue, and ends in a white tip, more or less extended depending on the flowers. The juxtaposition of all these two-toned flowers transforms the plant into a fascinating bouquet. The plant will reach approximately 1.20 m (4ft) in height and 60 cm (24in) in width and has a bushy habit. Its leaves, with a smooth texture, are divided into very denticulate lobes. The flowering of this variety begins in July and ends in October, if one takes care to remove faded flowers or make bouquets frequently.
Today, indispensable in gardens, Dahlias were initially cultivated in Mexico as a root vegetable. Their poor taste qualities quickly relegated them to the status of ornamental plant, but they are still welcome in vegetable gardens to bring a bit of color among the vegetables and supply the cut flower reserves. 'Deuil du Roi Albert', with its strong personality, can be used as a solitary plant, but will be magnified by a setting of grasses (Stipa, Pennisetum, Crested Wheatgrass, Carex...) or panicle phlox and white or red cosmos. It could also be paired with the old rose 'Deuil de Paul Fontaine', dark crimson red, in harmony of colour, and as a nod.

Planting and care
The Dahlia 'Deuil du Roi Albert' is easy to grow in all regions. For abundant flowering, it is good to follow a few simple rules. Plant the tubers in full sun as soon as the last frost is over. Rich, damp, and well-drained soil is perfect. However, waterlogging 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 bonemeal. Place your tuber and crumble the soil well to fill without air pockets. Your dahlia should be covered with about 6 cm (2in) of soil. At the end of planting, water generously once and then regularly repeat this watering during the first 6 weeks to help with rooting.
Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frost blackens the foliage, which is the time to dig them up. Carefully remove the tubers, removing as much soil as possible. Let the foliage dry so that the tubers can replenish their reserves. Then cut the stems to 10 cm (4in). Spread your bulbs in a box on newspaper. Store them in a frost-free, dry, cool, and dark place, such as a frost-free garage or attic, for example. In warmer regions, or areas close to the coast, where there are few frosty days per year, it is possible to leave them in place. In this case, simply cover the ground with a carpet of leaves or straw for protection.
This tall Dahlia, with its hollow stems, is not very resistant to wind or heavy rain. To overcome this inconvenience, you can stake it, but let's admit it, it's not very aesthetically pleasing. However, by pinching the stems early or removing the axillary flower buds, you can make the plant spread out, which will offer more resistance to bad weather. At the same time, you direct 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).
