Condition and quantity of the bulb are satisfactory, but at this stage of the year, I have not yet been able to admire the result, hence my 4-star rating instead of 5 on the evaluation.

Description
The Dahlia 'Fiorentina' is a very floriferous variety of Decorative Dahlia. The round, semi-double flowers are bicolour with bright red petals mixed with white, and they bloom from July to October.
This perennial has fleshy tuberous roots. Gathered in bundles, these tubers produce upright, hollow, and branching stems, bearing compound leaves with rounded leaflets. Strong, fleshy stems reach a height of 80cm (32in) and are topped with clusters of ligulate flowers measuring 8cm (3in) in diameter.
Dahlia 'Fiorentina' thrives in rich, clay, but well-drained and deeply worked soil, in a warm and sunny location, sheltered from prevailing winds. It struggles in poor, sandy soils.
Dahlia 'Fiorentina' is used in mixed flower beds with other varieties or for making bouquets.
Tips: When planting, consider the dimensions for the composition of your flower beds.

Planting and care
Dahlia 'Fiorentina' should be planted from mid-April to early May at a depth of 10 to 15cm (4 to 6in) and with a spacing of 60cm (24in). Always stake the plants and tie the young stems loosely. Apply slow-release compost or organic fertilizer during planting and liquid fertiliser once a month during the growing season. Water without wetting the foliage. There is no need to remove buds on this variety. Treat against aphids and slugs. Dig up the tubers before the frost, cutting the stems to 15cm (6in) from the stump. Store them in a cool, well-ventilated, dark place that is not too humid. Transplant in early May when the risk of frost has passed.

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.
