Unfortunately, the dahlias did not come up at all. I ordered them quite late. I hope to be able to plant them again next year.

Description
Dahlia 'Black Touch' has ligulate petals that are tapered and end in forked tips, giving the inflorescence a neatly tousled appearance. Its rich garnet red colour is populated with black reflections at the heart, which also reveal a few small greenish petals. This tall variety will benefit from being pinched to withstand the wind and produce more flowers. It blooms from July until the first frosts if faded flowers are regularly removed. It is perfect in the background of flower beds, accompanied by tall ornamental grasses and tall asters. The cut flowers are sublime in bouquets.
Dahlias belong to the Asteraceae family and are originally from the high plateaus of Mexico. There are currently thousands of horticultural varieties that have conquered gardens worldwide. They are tender perennials with fleshy tubers.
'Black Touch' will reach up to 1.5m (5ft) in height if the plant grows freely, and about 1.2m (4ft) if pinched during vegetative growth. It has a spread of 60cm (24in). It is classified as a fimbriated dahlia. This is a horticultural category defined by the shape of the flower. In this group, the tips of the petals seem to have been cut into forks. It flowers from July to October-November. The heads measure 12 to 14cm (5 to 6in) in diameter. The dark red ligules are marked with purple-pink and black. The habit is bushy and erect, and the highly branched stems are hollow. Its leaves are opposite and pinnately compound, meaning they are divided into 3 or 5 strongly toothed lobes. The leaves are medium green and the stems are purplish.
Remove faded flowers to encourage new blooms. You can use cut flowers to make colourful bouquets, combining them with other varieties.
'Black Touch' pairs particularly well with pink blooms, especially those of repeat-flowering roses (Rosa 'The Fairy', R. Pink Knock Out) or asters (Aster lateriflorus 'Horizontalis'). In a flower bed, it will perfectly match Geranium 'Blue Cloud', pink echinaceas, heleniums, and pastel-toned cosmos, for example. It will also create a beautiful combination with sedums and miscanthus.
Dahlias are stars of borders and ornamental gardens, confidently accompanying the most beautiful flowers. However, they are also appreciated alongside vegetable plants. In Mexico, this tuberous plant was first cultivated as a root vegetable for consumption. Its poor taste qualities quickly saw it categorised as an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care
Dahlias are easy to grow. They prefer rich and deep soil that is moist but not too wet. Enrich poor, sandy, or stony soil each year with compost or well-rotted manure.
Slugs are the main enemy of dahlias. In our garden, we have lost dahlia tubers because slugs were eating all the emerging buds, UNDERGROUND, without us seeing them. Today, when we plant dahlias in the most infested areas of slugs, we take care to start their growth by planting them in pots first. When the stems have reached about 20cm (8in) in height, we plant them in the ground because slugs are less fond of well-established stems. It is also easier to intervene, as the damage occurs on the visible parts and no longer underground.
Dahlias are sensitive to cold, so they need to be overwintered. Dig the tubers up when the first frost has blackened the foliage. 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 lined with newspaper. Store them in a frost-free, dry, cool, and dark place, such as a garage or attic. In mild regions without frost, or those close to the coast, 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.
