Description
The Dahlia 'Platinum Blonde' is a recent variety of robust, prolific, and refined anemone-flowered dahlia. It produces medium-sized bicoloured heads, composed of a simple white collar where a large cushion of tender yellow florets nestles, tending towards ivory. It blooms a little earlier than other varieties, from summer to autumn, at the top of a bushy clump. Proud in borders, this dahlia has enough distinction and personality to accompany tall perennials and flowering bushes without overshadowing them.
Dahlias are tuberous plants of the large Asteraceae family, originally native to the high plateaus of Mexico. Currently the approximately 25,000 horticultural varieties obtained by humans have invaded, to our pleasure, gardens all over the world. Dahlias are classified according to the shape of their flowers. Introduced in 2007, in the same vein as 'Blue Bayou' and 'Totally Tangerine' but in pastel yellow, 'Platinum Blonde' is classified in the category of anemone-flowered decorative dahlias. In this group, the colourful ligules of the head are arranged in fringed pompoms, for example, and surrounded by a collar of wider petals. In this variety, the heads are 7 to 10 cm (3 to 4in) in diameter and the outermost ligules are almost flat, arranged in a simple collar. Those in the centre are shorter, tubular, and fringed, of a bright pale yellow, pressed against each other like a cushion. The flowering takes place from the end of June to October. The vigorous plant will easily reach 1.2 metres (4 feet), or even more in fertile soil, with a bushy and dense habit. The highly branched stems are hollow and the leaves are opposite and divided into 3 or 5 denticulate leaflets. The leaves and stems are of a fairly deep green.
To promote continuous blooming and extend the flowering period, make sure to remove faded flowers. Even better, regularly compose attractive colourful bouquets by combining various varieties. This variety deserves to be highlighted by the light foliage of grasses such as Panicum, Molinia, and Calamagrostis. This combination will emphasise the contrast between the delicacy of the tall grasses and the assertiveness of the flower. The flowering of Cannas and Echinaceas is perfect as an accompaniment to that of Dahlias, as they occur simultaneously, as well as the flowering of cosmos or perennial salvias, for example.
The star plant of ornamental gardens, Dahlias are undoubtedly beautiful flowers. They are perfect in flower beds but can also enhance vegetable gardens. In Mexico, this tuber was initially cultivated as a root vegetable for consumption. Its poor taste quickly relegated it to the status of an ornamental plant. Since then, interest in their beautiful exuberance has never waned.

Planting and care
The 'Platinum Bronze' 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 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.
