Description
Dahlia Seniors Hope, like all the varieties of the Seniors series, is a new decorative dahlia of rather modest size, very flowering, with a truly unique color. It bears double flowers in balls, fully striped and variegated with old rose, garnet, purple and violet with a touch of golden cream, carried by almost black stems. Blooming late in the season, this next-generation Dahlia is also a strong and versatile plant that does not require staking. It has its place in a flower garden, is suitable for pot culture, and its long-lasting flowers can be used to create all kinds of bouquets. For us, it's a real favourite!
Dahlias belong to the aster family and are originally from the high plateaus of Mexico. At present, the approximately 25,000 horticultural varieties obtained by man have invaded, to our great pleasure, gardens all over the world.
The 'Seniors Hope' variety is a semi-dwarf Dahlia, it will not exceed 70 cm (28in) in all directions. It is also classified as a decorative Dahlia, which is a horticultural category defined by the shape of the flower. In this group, the coloured ligules of the head are arranged regularly in a spiral, they can be bent towards the stem or fringed, for example. The 'flowers' or heads of 'Seniors Hope', widely offered to the eye, almost globose, are about 12 cm (5in) in diameter. The ligules or 'petals' are oval in shape, in shells, which allows them to reveal a dark red garnet reverse contrasting with their lighter colour on the top. The overall composition is a baroque harmony combining different shades of pink, cream, and red to purple. The golden heart of the flower only appears late, just before fading. The flowering takes place from July to October. The habit is bushy and dense. The very branched stems are hollow and the leaves are opposite, pinnatisect, meaning they divide into 3 or 5 very toothed lobes. The shiny leaves are dark green, while the floral stems are almost black.
To promote flowering, take care to remove faded flowers, or better yet, regularly make large colourful bouquets by combining it with other varieties. 'Seniors Hope', with its strong personality, will form remarkably colourful spots in flower beds. Plant it, for example, with pink Echinaceas that bloom at the same time, or with Asters. Japanese anemones are good companions for the late season, as are ornamental grasses (compact Miscanthus, Pennisetum, Stipa, Muhlenbergia capillaris, Eragrostis spectabilis). This modest-sized variety is well suited for pot culture, to easily adorn the patio or balcony.
As a star plant in curative 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 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 'Seniors Hope' 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 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.

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.
