Description
The 'Duke Duweno' Dahlia is a difficult-to-find variety, with inflorescences that resemble beautiful, regular, and perfectly rounded pompoms. It produces a profusion of flowers from July to October, with a beautiful violet-purple colour enriched with magenta highlights, stunning next to pink or 'black' flowers, for example. Not exceeding a height of 80cm (32in), with a bushy habit, the plant produces excellent cut flowers. It will also be appreciated in sunny borders and the heart of flower beds. It is also suitable for container cultivation.
Dahlias belong to the Asteraceae family and are originally from the high plateaus of Mexico. Currently, the approximately 25,000 horticultural varieties obtained by humans have invaded gardens worldwide, much to our delight.
The 'Duke Duweno' variety is classified either among decorative Dahlias or ball Dahlias, which is a horticultural category defined by the shape of the flower. In this group, the heads are larger than those of pompom Dahlias, produced abundantly, and the tubular ligules form a more or less spherical or flattened inflorescence that has a regularly alveolate structure, like a beehive. The flowers of 'Duke Duweno' have a diameter of about 7-8cm (3in). Their colour is quite rare, blending different shades of purple, burgundy, violet, with magenta highlights in the sun. The flowering period is from July to October. The habit is particularly bushy. The highly branched stems are hollow, and the leaves are opposite, pinnately lobed, meaning they are divided into 3 or 5 very toothed lobes. The leaves and stems are a bright green colour.
To promote continuous flowering, make sure to remove faded flowers, or better yet, regularly make large colorful bouquets by combining them with other varieties. 'Duke Duweno' pairs particularly well with very dark flowers or different shades of pink, English roses, and the mauve colours found in paniculate phlox. In flower beds, this Dahlia will create highly colourful spots in the company of Echinaceas and fox-tail Amaranthus, for example, which bloom at the same time, as well as daylilies and asters. This variety with its highly flowered stems allows for the decoration of bouquets until late in the season.
As a star plant in borders and herb gardens, Dahlias confidently accompany the most beautiful flowers but are also appreciated alongside vegetable plants. In Mexico, this tuber was initially cultivated as a root vegetable for consumption. However, its poor taste qualities relegated it to the status of an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care
The Dahlia 'Duke Duweno' is easy to grow in all regions. For abundant flowering, it is good to follow a few simple rules. Plant the tubers in a sunny location as soon as the last frost has passed. Rich, fresh, and well-drained soil is 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. Place your tuber and crumble the soil to fill without air pockets. Your dahlia should be covered with about 6cm (2in) of soil. At the end of planting, water once abundantly and then regularly renew this watering during the first 6 weeks to aid in rooting. Dahlias are sensitive to cold, so they must be overwintered. In November, the first frost causes the foliage to turn black, which is the time to dig them up. Carefully remove 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 10cm (4in). Spread your bulbs in a box on newspaper. Store them in a frost-free, dry, cool, and dark place, such as a garage or attic. In southern regions, close to the coast, where there are few days of frost 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.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
