Description
Dahlia ‘Karma Purple Corona’ is a cactus or semi-cactus dahlia in a purple-violet shade, bred for cut flowers. It is highly prized for its large, exotic-looking blooms with a very rich colour. Its inflorescences make a beautiful statement in the garden as well as in cut flower arrangements, in a very contemporary style. It is also distinguished by its long, rigid stems and its excellent vase life. In a border, ‘Karma Purple Corona’ introduces an intensely sophisticated note.
Dahlias belong to the Asteraceae family and originate from Mexican species. They are non-hardy perennials with tuberous roots, which above-ground parts die back in winter. Their stump is formed of fleshy tubercles which must be protected from the cold in winter.
Dahlia ‘Karma Purple Corona’ is a mutation of the variety ‘Karma Corona’. It is part of the Karma collection, a line of dahlias carefully selected by the Verwer brothers in the Netherlands for professional cut flower production. The Karma dahlias are renowned for their robust stems and long-lasting blooms once cut. This cultivar is officially classified among the cactus dahlias: its flowers are double, formed of narrow, rolled, pointed, slightly recurved "petals", which create a dense, bristly star. Its inflorescences reach 13-14 cm in diameter. Their colour is described as violet to reddish-purple: a deep, saturated violet tone, with reddish-purple highlights and an almost velvety texture. The plant forms an upright clump approximately 90 cm in height, with an erect habit. The sturdy stems support the weight of the flowers without drooping. The foliage, formed of the typical divided leaves of dahlias, creates a dense mass of beautiful dark green.
Dahlia ‘Karma Purple Corona’ has a theatrical style; its graphic form deserves companions of character. In a border, you can pair it with the bluish hues of Dahlia ‘Karma Lagoon’ or the deep red of ‘Sam Hopkins’. Add a few stems of Dahlia ‘Honka Fragile’ to lighten the overall effect. The dark plumes of Purple Common Millet or the soft spikes of Amaranth ‘Velvet Curtains’ will create a large, florist-style cut flower arrangement directly in the garden. In a vase, all these varieties combine to make armfuls of chic, bold violet, where ‘Karma Purple Corona’ is the star, enhanced by fine textures and rich colours.

Planting and care
Dahlia 'Karma Purple Corona' is easy to grow in all regions. For generous flowering, it is good to follow a few simple rules: plant the tubercles in full sun after the last frosts; rich, cool, and well-drained soils are perfect. However, stagnant moisture would encourage the tubercles to rot. Do not hesitate to amend the soil with compost and sand if needed. Work the soil deeply and enrich it, for example, with ground horn or dried blood. Place your tubercle and crumble the soil well to fill in without air pockets. Your dahlia should be covered with about 6 cm of soil. At the end of planting, water thoroughly once, then repeat this watering regularly for the first 6 weeks to aid rooting.
Dahlias are sensitive to cold and need to be overwintered. In November, the first frosts blacken the foliage; this is the time to lift them. Dig up the tubercles carefully. Remove as much soil as possible. Allow the foliage to dry so the tubercles can replenish their reserves. Then cut the stems to 10 cm. Spread your bulbs in a crate on newspaper. Store them in a frost-free, dry, cool, and dark place, such as a frost-free garage or an attic. In southern regions, near the coast, experiencing only a few frosty days per year, it is possible to leave them in place. In this case, simply cover the soil with a carpet of leaves or straw for protection.
Tall Dahlias, with hollow stems, do not withstand wind or heavy rain well. To overcome this drawback, you can stake them, but, you must admit, it is not very aesthetic. On the other hand, by pinching the stems early or removing the axial flower buds, you will spread the habit of the plant, which will offer more resistance to bad weather. At the same time, you thus duct the influx 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).
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.
