Outstanding! Planted in large pots, they continued to bloom all summer long without interruption. Perhaps 30 or 40 flowers constantly blooming for each plant. Magnificent. Truly magnificent.

Description
Dahlia Tropical brings something new to the world of decorative Dahlias: its large flowers are arranged in a frilly pattern of randomly striped and speckled petals in shades of purple and violet on a light raspberry pink background. With their appearance of variegated roses, both sparkling and precious, they attract all eyes in the garden and allow for the creation of trendy bouquets with a carefully studied mess, inspired by still life paintings of Flemish masters. Of modest stature, well-branched, the plant will be appreciated in sunny borders, among low bushes, and in a large pot on the patio.
Dahlias belong to the Asteraceae family and are originally from the high plateaus of Mexico. Currently, the approximately 25,000 horticultural varieties obtained by humans have arrived in gardens around the world, much to our delight.
The 'Tropical' variety, recently introduced into horticultural trade, is 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 capitulum are arranged regularly in a spiral, they can be curved towards the stem or even curled. In this variety, the inflorescences in capitula are about 12 cm (5in) in diameter and their ligules or petals are slightly twisted in a spiral. Each flower has its own personality, combining different patterns of dark pink, purple, or violet on a lighter pink background. Flowering takes place from July to October. The habit is well-branched, with the plant reaching about 80 cm (32in) in height when in bloom and 50-60 cm (20-24in) in width. The very branched stems are hollow and the leaves are opposite, pinnately compound, meaning they are divided into 3 or 5 very toothed lobes. The leaves and stems are a medium greenish-blue in this variety.
To promote continuous flowering, make sure to remove faded flowers, or even better, regularly make large colourful bouquets by combining it with other varieties. 'Tropical' alone creates the decor for a dedicated bed, but its flowers will be enhanced by lighter and more discreet blooms, such as those of panicled baby's breath, chamomiles, or a white Linaria purpurea. In beds, this dahlia pairs well with phlox in shades of mauve, a 'The Fairy' rose, blue bellflowers, and white, blue, or mauve autumn asters, for example. This variety with its heavily blooming stems allows for the addition of flowers to bouquets well into the late season.
As a star of borders and cottage gardens, Dahlias confidently accompany the most beautiful flowers but are also appreciated alongside vegetable plants. In Mexico, this tuberous plant was first cultivated as a root vegetable for consumption. However, its poor taste qualities assigned it the status of an ornamental plant.

Planting and care
Dahlia 'Tropical' 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.
