Description
This Collerette Dahlia 'Hartenaas' is a rather compact variety, very floriferous, well suited for perennial beds, borders, and flowering pots. Its pink flower, of modest size, well open, is adorned with a pretty tone-on-tone collar and a golden centre that bees love. A simple and charming flowering, which is renewed for several weeks.
Dahlias belong to the Asteraceae family and are originally from the high plateaus of Mexico. At present, the thousands of horticultural varieties obtained by humans have invaded, to our great pleasure, gardens all over the world. The Dahlia is a herbaceous perennial plant due to its tuber, a reserve organ that allows it to pass the bad season in a resting and dry state.
The 'Hartenass' variety is classified among the Collarette Dahlias, which is a horticultural category defined by the shape of the flower. In this group, the coloured ligules of the head are regularly arranged in a crown around a collar of small petals surrounding the central disk. The 'Hartenaas' flowers are approximately 7-8cm (3in) in diameter. The flowering takes place from July to October. The habit is bushy, with the plant reaching approximately 55cm (22in) in height. The very branched stems are hollow and the leaves are opposite, pinnately lobed, which means they are divided into 3 or 5 very toothed lobes. The leaves are green and the stems are more or less tinged with copper.
To promote flowering again, take care to cut faded flowers, or even better, regularly make large colourful bouquets by associating it with other varieties. 'Hartenaas' goes particularly well with white flowers (foxgloves, baby's breath) or mauve ones (Nepetas, Agastache Serpentine, Anchusa 'Dropmore'). The dark foliage of Physocarpus or Anthriscus sylvestris 'Ravenswing' also enhances its very pretty pink flowers.
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 first cultivated as a root vegetable for consumption. But its poor taste qualities assigned it to the rank of an ornamental plant.

Planting and care
Plant your dahlias during the good weather in soil that has been deeply tilled and enriched, for example, with crushed horn or dehydrated blood. Place your tubercle and crumble the soil well to fill in without any air pockets. Your dahlia should be covered with 6cm (2in) of soil. At the end of planting, pour one litre of water. Water regularly during the first 6 weeks to help with rooting. Dahlias are sensitive to cold. They need to be overwintered. In November, the first frost will blacken the foliage, which is the time to dig them up. Carefully remove the tubercles. Remove as much soil as possible. Let the foliage dry so that the tubercle can replenish its reserves. When the foliage is dry, cut the stems 10cm (4in) from the tubercle. Spread your bulbs in a box on newspaper. Store in a frost-free, dry, cool, and dark place.

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.
