Description
The 'Yvonne' camellia-flowered Dahlia is a vigorous variety, quite rare in cultivation, offering adorable double flowers full of freshness. Of medium size, slightly flattened, they resemble waterlilies. Their colour is a very fresh medium pink in the centre, with the peripheral petals being lighter and tinted with salmon pink. This dahlia with its beautiful dark green-grey foliage has a long summer flowering period, overflowing with charm until the first frost, perfect for adding a romantic and feminine touch to borders or in bouquets.
Dahlias belong to the large family of Asteraceae, originally from the high plateaus of Mexico. Currently, the approximately 25,000 horticultural varieties obtained by humans have arrived, to our greatest pleasure, in gardens worldwide. Varieties of Dahlias are classified according to the shape of their heads. 'Yvonne' is a Dahlia from the decorative group with camellia-like flowers. The terminal inflorescences, called heads, are carried by dark stems. They are composed of several rows of almost flat outer ligules, slightly curled. The heads are regular and generally measure 8 to 9 cm (3 to 4in) in diameter. The outermost ligules are more or less pale pink to soft salmon pink, while those in the centre are a brighter, more vibrant pink. The small yellow centre of the flowers only appears late, just before fading. The plant will easily reach a height of more than 1.20 m (4ft) and a width of 60 cm (24in). It has an erect habit, and its tall stems often require staking. Its beautiful dark green leaves are divided into finely toothed lobes. The particularly long flowering period of this variety begins in July and ends in October-November, if care is taken to remove faded flowers or frequently make bouquets.
Today, essential in gardens, whether ornamental or even in vegetable gardens, Dahlias were initially cultivated in Mexico as a root vegetable. Their poor taste qualities quickly relegated them to the status of ornamental plants, but they are still welcome in vegetable gardens to add a splash of color amidst the vegetables. 'Yvonne' is a tall plant that can be used to structure elevated borders, and can be paired with purple foliage, for example (Cotinus Royal Purple, Physocarpus 'Red Baron', Sambucus nigra 'Black Lace'). It particularly goes well with blue, plum, or even chocolate-coloured flowers.

Planting and care
Dahlia 'Yvonne' is easy to grow in all regions. For a generous flowering, it is good to follow a few simple rules. Plant the tubers in full sun as soon as the last frost is over. Rich, damp, and well-drained soil is perfect. However, waterlogging 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 bonemeal. Place your tuber and crumble the soil well to fill without air pockets. Your dahlia should be covered with about 6 cm (2in) of soil. At the end of planting, water generously once and then regularly repeat this watering during the first 6 weeks to help with rooting.
Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frost blackens the foliage, which is the time to dig them up. Carefully remove the tubers, removing as much soil as possible. Let the foliage dry so that the tubers can replenish their reserves. Then cut the stems to 10 cm (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 warmer regions, or areas 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 carpet of leaves or straw for protection.
This tall Dahlia, with its hollow stems, does not withstand wind or heavy rain well. 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 habit of the plant, which will offer more resistance to bad weather. At the same time, you channel the flow of sap to a single flower that 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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
