Description
Dahlia 'Knock Out' or 'Mystic Illusion', is a very recent New Zealand variety. The compact vegetation presents an interesting contrast of colours. The heads are single, tinted with pale yellow finely veined with purple-brown, the small heart in the centre is brown-gold. All this is carried by solid and surprisingly dark leafy stems, of a chocolate to almost black purple colour. An unclassifiable, innovative and disease-resistant variety, as beautiful from a distance, abundant in a bed, as fascinating observed up close, immersed in a vase!
Dahlias belong to the aster family and are originally from the high plateaus of Mexico. Currently, the few 25,000 horticultural varieties obtained by humans have arrived in gardens all over the world, for our greatest pleasure. The 'Knock Out' variety is a Dahlia with dark foliage that will reach 80 to 90 cm (32 to 35in) in height and 50 to 60 cm (20 to 24in) in width. Single, the heads are medium-sized. The outermost ligules are light yellow and are covered, particularly on their lower surface, with pretty reddish veins. The tiny flowers in the center form a fairly dark brown disc, adorned with orange stamens. Flowering occurs from July to October. The habit is bushy and compact. The very branched stems are hollow and the opposite leaves are divided into 3 or 5 toothed lobes. The leaves and stems are of a very original colour, bronze, purple, chocolate, almost black, and really enhance the colour of the heads. This variety often does not require staking.
To encourage repeat flowering, be sure to cut off faded flowers, or even better, regularly make large colourful bouquets by combining it with other varieties. 'Mystic Illusion' pairs particularly well with the 'Classic Elise' variety (also with dark foliage) and the grey foliage of wormwoods (Powis Castle Wormwood, Lambrook Silver Artemisia absinthium) or the dark needles of certain small conifers (Chirimen Hinoki Cypress, Juniperoides Hinoki Cypress). In beds, this exceptional Dahlia will form colorful and bright spots alongside Echinaceas, for example, which bloom at the same time, as well as blue or purple Asters with light flowering. Its flowers are of course magnificent in bouquets.
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 tuberous plant was initially cultivated as a root vegetable for consumption. But its poor taste qualities assigned it the status of an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care
Dahlia 'Mystic Illusion' is easy to grow in all regions. For a generous 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.

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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
