Description
The 'Bahia Blanca' decorative Dahlia presents us with its lovely little white flowers, whose rounded shape and regularity recall ball Dahlias. A candid flower, with only its little heart warmed with cream. They are borne at the end of thin but sturdy stems, well suited for making bouquets. The spectacle of this elegant and luminous flowering is constantly renewed from July until the first frost.
Dahlias are tuberous plants from the large Asteraceae family, originally from the high plateaus of Mexico. Currently, the thousands of horticultural varieties obtained by humans have invaded, to our greatest pleasure, gardens all over the world. Dahlias are classified according to the shape of their flowers. 'Bahia Blanca', registered in the Netherlands in 2021, is classified in the category of decorative Dahlias. In this group, the colourful ligules of the head are arranged regularly in a spiral, they can be bent towards the stem or curled, for example. In this variety, the heads measure 12cm (5in) in diameter and their ligules are rather small, oval, partially rolled up, arranged regularly. Flowering takes place from July to October-November. The plant reaches about 1m (3ft) in height, and 50 to 60cm (20 to 24in) in width, with a bushy and erect habit. The very branched stems are hollow and the leaves are opposite, pinnatisect, meaning they are divided into 3 or 5 leaflets, which form very denticulate lobes. The leaves are a fairly dark green and the stems, sturdy, are a lighter green.
To promote new flowerings and extend the flowering period, take care to remove faded flowers. Even better, regularly compose attractive colourful bouquets by combining different varieties. Decorative Dahlias go well with medium-height ornamental grasses and Gauras that lighten their generous silhouette. Their flowers also allow for numerous associations in floral compositions. The medium size of this variety makes it suitable for the centre of mixed borders, to structure an ensemble composed of Weigela x florida Ebony and Ivory® shrubs, for example. The flowering of Echinaceas is perfect to accompany that of Dahlias, as they occur simultaneously.
As a star plant in cottage gardens, Dahlias are undoubtedly essential flowers in the garden. They are impeccable in flower beds, but can also enhance the vegetable garden. In Mexico, this tuberous plant was first cultivated as a root vegetable for consumption. Its poor taste qualities quickly relegated it to the status of an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care
The 'Bahia Blanca' decorative Dahlia 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 after the last frost, rich, fresh, and well-drained soil is 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 without air pockets. Your dahlia should be covered with about 6cm (2in) of soil. At the end of planting, water once abundantly and then regularly water for the first 6 weeks to aid in rooting.
Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frost blackens the foliage, and that's 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 in a frost-free, dry, cool, and dark place, such as a frost-free garage or attic, for example. In southern regions, close to the coast, where there are few days of frost 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 still sensitive to strong winds or heavy rains. To overcome this inconvenience, you can stake it, but let's agree, it's not very aesthetic. On the other hand, by pinching the stems early or removing the axial flower buds, you will spread out the plant's habit, which will offer more resistance to bad weather. At the same time, you are channeling 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).
