Description
Helianthus annuus, or Garden Sunflower is an annual plant with rapid growth and strong branching stems that can reach up to 1.80m (3.3ft) in height, making it ideal for flowering in the back of flower beds.
Its tricoloured flowers resemble giant daisies (15 to 20cm (5.9 - 7.9in) in diameter). Their brown, almost black centre is surrounded by a triple row of red-mahogany petals with yellow tips.
A single branch provides enough flowers to create a splendid summer bouquet. (Producing little pollen, the flowers will not stain your furniture.)
This impressive flowering period extends from July to October.
Until it starts flowering, the plant optimizes its growth by following the sun's path. This phenomenon, called heliotropism, has given rise to some of its common names: Heliotrope, Sunflower, Garden Sunflower, Sunflower...
Ecologically speaking:
The melliferous flowers will attract butterflies and pollinating insects to your garden.
The oil-rich seeds are particularly appreciated by birds (Parrots, Tits...). At the end of the flowering period, harvest them to bring happiness during the winter scarcity.

Planting and care
The Sunflower can be sown: either in March-April, in pots under shelters, for the preparation of young plants that can be planted in your flower beds after the last frosts. Or from April to June, after the frosts, directly in place. In a sunny spot in your garden. Sow your seeds in groups of 2 at a depth of 1cm (0.4in) and spaced 50cm (19.7in) apart. After 20 days, remove the weakest shoot to keep only one per location. The strong growth of the Sunflower will require regular watering. When the plant reaches about 1.50m (3.3ft), watering can be stopped and it can rely on rainfall, even if it is scarce. Protect your seedlings from attacks by snails and slugs, which are fond of these young plants.

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.
