Description
The Dahlia 'Rock and Roll' is an anemone-flowered dahlia. A beautiful flowering plant that harmoniously combines the red of the flat ligules of the crown with the golden yellow of the central pin cushion.
Dahlias belong to the large asteraceae family and are originally from the high plateaus of Mexico. At present, the approximately 20,000 horticultural varieties created by humans have invaded gardens all over the world, much to our delight. Dahlias are classified according to the shape of their flowers. 'Rock and Roll' is an anemone-flowered dahlia. The inflorescences have one to two rows of revolute outer ligules (turned towards the stem) and a wide central disc composed of a collection of long, thin ligules that resemble a pin cushion. The heads of this variety are 10 cm (4in) in diameter. The crown is a magnificent red colour. The central florets are a beautiful golden yellow, some with red markings. The plant will reach a height of 100 cm (39in) and a width of 70 cm (28in), with a bushy habit. As a large variety, it is important to ensure that it is well-branched to strengthen its structure, as the stems of dahlias are hollow. Its leaves are opposite and pinnatisect, meaning they are divided into 3 or 5 leaflets, which have very denticulate lobes. The leaves and stems are dark green.
The flowering period of dahlias is exceptionally long, starting in July and ending in November or first frost. To encourage continuous blooming, make sure to remove faded flowers. Even better, regularly cut them to create attractive colourful bouquets, combining different varieties. In the middle of a flower bed, these dahlias will create colourful spots alongside large echinaceas, sedums, or perennial salvias, for example. When paired with Pennisetum villosum, the combination will have a delicate and soft effect.
The star plant of cottage gardens, dahlias are undoubtedly beautiful flowers. They look impeccable in a flower bed but can also enhance a vegetable garden. In Mexico, these tuberous plants were initially cultivated as root vegetables for consumption. Their poor taste quickly relegated them to the status of ornamental plants. Since then, the appreciation for their beautiful exuberance has never waned.

Planting and care
The 'Rock and Roll' Dahlia is easy to cultivate 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. 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 well to fill the hole without air pockets. Your dahlia should be covered with about 6 cm (2in) of soil. At the end of planting, water abundantly once and then regularly for the first 6 weeks to help with rooting.
Dahlias are sensitive to cold, they need to be overwintered under shelter. In November, the first frosts blacken the foliage, so it is time to dig them up. Carefully unearth the tubers. Remove as much soil as possible. Let the foliage dry so that the tubers can replenish their reserves. Then cut the stems down to 10 cm (4in). Spread your bulbs in a crate on newspaper. Store them protected from frost in a dry, cool, and dark place, such as a frost-free garage or an attic. In the southern regions, 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 layer of leaves or straw for protection.
This tall dahlia, with its hollow stems, is not resistant to wind or heavy rain. To overcome this drawback, you can stake it but it's not very attractive. On the other hand, by pinching the stems early you can spread out the habit of the plant, which will offer more resistance to bad weather. Alternatively, you can remove the axillary flower buds to channel the flow of sap to a single flower, which will become larger and sturdier, though taller.

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.
