Description
Dahlia 'Edge of Joy' is one of those new varieties of Decorative Dahlias that is quite unique, standing out for the shape and colour of its flowers. This one, truly original, produces not very large, well-opened, semi-double, swirling flowers, overall bicolored, in shades of white, pink, mauve, and deep purple, from fuchsia to intense magenta. They are carried well above the foliage by sturdy stems, perfect for cutting. And the spectacle of this flowering is constantly renewed from July until the frosts.
Dahlias are tuberous plants from the large Asteraceae family. They are originally from the high plateaus of Mexico. At present, the thousands of horticultural varieties obtained by humans have invaded, much to our delight, gardens all over the world. Dahlias are classified according to the shape of their flowers. 'Edge of Joy' is classified in the category of Decorative Dahlias. In this group, the coloured ligules of the head are regularly arranged in a spiral, they can be bent towards the stem or fringed, for example. In this variety, the heads measure only 8cm (3in) in diameter and their ligules are rather large, widely ovate, slightly twisted, and loosely arranged. The flowering takes place from July to October. Depending on the ripeness of the flower, the colour of the ligules or 'petals' varies from pure white to more or less mauve pink, and the magenta pattern is more or less extensive. The plant will reach a height of about 90cm (35in), and 50 to 60cm (20 to 24in) in width, with a bushy and erect habit. The very branching stems are hollow and the leaves are opposite, pinnately compound, meaning they are divided into 3 or 5 leaflets, which form very denticulate lobes. The leaves and stems are a medium green.
To promote 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 Gauras and Cleomes, which will lighten their generous silhouette. The flowers of 'Edge of Joy' also make wonderful bouquets, with dahlias or purple roses, for example. The average size of this variety makes it suitable for the centre of mixed borders, to structure a composition of bushy plants and lower-growing plants. The flowering of Echinaceas is perfect to accompany that of Dahlias, as well as that of perennial salvias, for example.
As the star plant of cottage gardens, Dahlias are undoubtedly beautiful flowers. They are perfect 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 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 decorative Dahlia 'Edge Of Joy' is easy to grow in all regions. For 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 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 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 renew 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 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 frost-free garage or an attic, for example. 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 overcome 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 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, 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).
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.
