Description
Centaurea cyanus Classic Fantastic, also called cornflower or bachelor's button, is a mixture of blue, white and sometimes bicoloured, single or semi-double flowers. Like the adorable annual weed which once so widespread in our countrysides, even wandering as far as into our cereal fields, it paints a somewhat naive but unforgettable picture. Very decorative in large drifts, these cornflowers are perfect in wildflower bouquets and bloom for months on end if care is taken to remove the flowers as they wilt. They like full sun and fertile, well-drained soil.
Cornflowers of the 'Classic Fantastic' variety belong to the family Asteraceae. It is a selection of cultivars derived from Centaurea cyanus, an annual herbaceous plant native to Europe and North Asia that has long been considered an invasive weed in cereal crops and is one of the most beautiful wildflowers of our regions. It forms an upright clump with tender stems, reaching 65 cm high and 30 cm wide, bearing very narrow, long, greyish-green leaves. The flowering period lasts from June to August, displaying inflorescences in the form of semi-double or single flower heads, 3 cm across. The ligulate flowers (or the petals surrounding the centre) are toothed at their tips and come in a blend of colours ranging from pure white to ultramarine blue, including a deep and very luminous azure blue. Some flowers are bicoloured, displaying both shades of white and blue. The centre of the inflorescence is made up of purplish florets. The flowers are very melliferous and nectar-rich.
Cornflowers are enchanting in flowerbeds where they form remarkable patches of colour. The mixture 'Classic Fantastic', delicious descendants of the most famous of them all, bring the charm of the countryside to our gardens. Sow cornflower in wild-looking beds, combined with ornamental grasses such as Stipa tenuifolia or Muhlenbeckia capillaris, catnips, with pink love-in-a-mist, California poppies and purple cornflowers. The edible flowers can be used to decorate summer salads. It is also an excellent cut flower.

Planting and care
Sow cornflower 'Classic Fantastic' seeds outside, in their final positions, in March-April. Choose a sunny spot with well-drained soil that has been well-prepared and raked to a fine tilth. Sow thinly, to a depth of 3 mm, spacing the seeds 30 cm apart. Water regularly, especially during dry periods. Germination usually takes 14-21 days. When the cornflower seedlings are large enough to be handled, transplant them 15 cm apart. An alternative is to sow them indoors from August to September to obtain blooms at the beginning of summer, the following year. Sow the cornflowers on the surface of good quality soil at a temperature of 18-23 °C, and cover with a sprinkling of very fine garden compost or vermiculite. Keep the seedlings in the light as this helps germination. When the seedlings are large enough to be moved, transplant and grow them in a place sheltered from the cold until the seedlings are large enough to be moved outside. Grow the cornflower seedlings in a frost-free place before planting out the following spring, or pricking them out in pots. Cornflowers thrive in fertile, well-drained, fine tilth soil, in full sun.

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.
