I haven't planted it yet as there's no shoot. Last year the same thing happened with a dahlia that I planted anyway; it produced nothing and even disappeared completely!

Description
The 'Parasol' Decorative Dahlia offers us a lovely, unpretentious yellow flower, with the delicacy of the petal edges adorned with reddish-brown, like a light brushstroke that has been washed out. This effect is more pronounced at the heart of the flower. Semi-double, well-opened, the rather small flowers are carried well above the foliage by sturdy, dark-coloured stems. The sight of this vibrant 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. Nowadays, the thousands of horticultural varieties obtained by humans have invaded, to our great pleasure, gardens all over the world. Dahlias are classified according to the shape of their flowers.'Parasol' is classified in the category of Decorative Dahlias. In this group, the coloured ligules of the head are arranged regularly in a spiral, they can be bent towards the stem or even fringed for example. In this variety, the heads measure 14cm (6in) in diameter and their ligules are rather large, quite narrow, almost flat, and loosely arranged. Flowering takes place from July to October-November. The plant reaches an average height of 1m (3ft), and 50 to 60cm (20 to 24in) in width, with a bushy and erect habit. The highly branched stems are hollow and the leaves are opposite, pinnately compound, meaning they are divided into 3 or 5 leaflets, which have very denticulate lobes. The leaves are a fairly dark green and the stems, particularly sturdy, are more or less tinged with purple.
To promote repeat flowering and extend the flowering period, be sure to remove faded flowers. Even better, regularly create attractive colourful bouquets by combining various varieties. Decorative Dahlias go well with Crocosmias, sages, for example, which lighten their generous silhouette. The cheerful flowers of 'Parasol' also allow numerous combinations in floral compositions. The medium height of this variety makes it suitable for the centre of mixed borders, to structure a composition composed of shrubs with purple foliage in contrast, such as Cotinus and Loropetalum, and lower plants. The flowering of Echinaceas is perfect to accompany the Dahlias, as they bloom simultaneously. Also consider golden grasses such as Stipa, Panicum, or Miscanthus which take on beautiful autumnal colours.
A star plant in ornamental gardens, Dahlias are undoubtedly beautiful flowers, they are impeccable in flower beds, but can also enhance the vegetable garden. In Mexico, this tuberous plant was initially cultivated as a root vegetable for consumption. Its poor taste qualities quickly assigned it the status of an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care
The 'Parasol' decorative Dahlia is easy to grow in all regions. To ensure abundant flowering, it is good to follow a few simple rules: plant the tubers in full sun as soon as the last frost has passed, 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 with crushed horn or dehydrated blood, for example. 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 during the first 6 weeks to aid in rooting.
Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frosts cause the foliage to turn black, which is 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 crate on newspaper. Store them in a frost-free, dry, cool, and dark place, such as a garage or attic. In southern regions, close to the coast, where there are only a 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 counter this inconvenience, you can stake it, but let's admit it, it's not very aesthetic. On the other hand, by pinching the stems early or removing the axial flower buds, you can 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, which will become larger and sturdier.

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.
