Description
Dahlia 'Rainbow Silence' is a magnificent variety with cactus flowers, offering large, graphic and brilliantly coloured flowers, from summer to autumn. Its beautiful inflorescences display a very bright coral pink colour, illuminated by a soft yellow centre, which truly catches the eye. This medium-sized variety is well suited to the back of perennial borders and its flowering shines among grasses or companion bush roses in harmonious colours. Its flowers are very long-lasting in bouquets.
Dahlias are tuberous plants from the large family of Asteraceae, originally from the Mexican highlands. Currently, the thousands of horticultural varieties have invaded, to our great pleasure, gardens all over the world. They are non-hardy perennials with fleshy tubers. The 'Rainbow Silence' variety, registered in 2019, will reach about 1m (3ft) in height, depending on growing conditions, with a spread of 60cm (24in). It is classified among the Cactus Dahlias; this is a horticultural category defined by the shape of the flower. In this group, the coloured "petals" or ligules of the head curl, giving them a characteristic pointed appearance. Flowering of this variety begins in July and ends in October-November. The heads measure 15-16cm (6in) in diameter. The habit is bushy and erect, and the highly branched stems are hollow. Its leaves are opposite, compound, meaning they are divided into 3 or 5 toothed lobes. The leaves are a medium green, with more or less purple stems.
To extend the flowering period and promote repeat flowering, make sure to remove faded flowers. Even better, regularly cut them to create attractive colourful bouquets by combining several varieties. 'Rainbow Silence' pairs particularly well with purple blooms, especially those of roses, but also with the spikes of Hordeum jubatum (squirrel-tail barley). In borders, it will perfectly complement blue hardy geraniums, catnips, as well as blue or purple salvias, for example.
As a star plant for borders and ornamental 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 rank of ornamental plant.

Planting and care
Dahlia 'Rainbow Silence' 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 soils are perfect. However, stagnant moisture would promote tuber rot. Do not hesitate 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 well to fill without air pockets. Your dahlia should be covered with about 6cm (2in) of soil. At the end of planting, water generously once and then repeat this watering regularly for the first 6 weeks to help with rooting.
Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frosts cause the foliage to blacken, 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 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, where there are only a few days of frost per year, it is possible to leave them in place. In this case, simply cover the soil with a layer 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 agree, it is not very aesthetic. On the other hand, by pinching the stems early or removing the axial 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).
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.
