Description
Dahlia 'Prince Valiant' is a summer bulb from the category of Decorative Dahlias. This generous Dahlia offers an abundant flowering from July to the first frost.
Its large double ball flowers measure 18 cm (7in) in diameter, with petals white speckled and striated with carmine red. Its pretty flowers can be cut to make beautiful bouquets.
It is a large-sized Dahlia that can reach a height of 1.20 m (4ft). This non-hardy plant originates from Mexico. It was first grown for its edible roots, which did not meet any success. It was admired more for its flowers, which were picked to make charming fresh bouquets. Neglected, it is making a comeback in gardens and on the tables of our homes.

Planting and care
Dahlia 'Prince Vaillant' appreciates sunny spots in your garden. Place it in a soil of ordinary type, rich in humus, sandy, fairly fertile, and well-drained. Plant the bulbs at a depth of 10 cm (4in), spaced 40 cm (16in) apart. Planting should take place after the last frost, from May to June. Easy to cultivate, provide a nitrogen-rich fertiliser until the end of June, then a potassium-rich fertiliser from July to October. These supplements should be applied once a week and will be beneficial for extending the flowering period. After planting, water regularly at the base, preferably in the evening, avoiding wetting the foliage. Watering is imperative during hot periods. Regularly remove faded flowers. After flowering, bring the bulbs indoors to a dry and well-ventilated place, if possible in sand and protected from rodents. A cellar is an ideal location. Before bringing them indoors, leave some leaves in place so that the bulb can replenish its nutrient reserves, and wait for these leaves to turn yellow. You can replant them in spring.

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.
