Description
Helianthus annuus 'Claret' F1 is a gorgeous hybrid variety that produces dark, wine-red blooms on branching, multi-headed plants. Perfect to bring contrast to sunny borders and summer bedding schemes. Sunflowers are popular annuals that are generally direct sown in spring in ordinary, well-drained garden soil.
Sunflower, or Helianthus annuus in latin, is a large annual plant belonging to the Asteraceae family, native to the Americas. It has long been domesticated for its edible seeds and is now cultivated on a large scale for its oil. 'Claret' F1 rapidly grows to a height of 120-150cm. It produces several pollen-free flowerheads (capitulum) per plant, each measuring 8-12cm across. The 1-2 layers of external petals (technically, ray flowers) are dark wine-red, arranged around a blackish central disc. The flowering period lasts from July to September. In ideal growing conditions, flowers appear 12-14 weeks after sowing. The floral stems are strong and branched, covered in simple, alternate to opposite heart-shaped green leaves. They are carried on a fairly long petiole and are rough to the touch.
This easy-to-grow plant, with its large seeds and cheerful disposition, is perfect for introducing children to gardening. It is particularly suited to sunny borders, low summer bedding schemes, rock gardens or even large containers. All it requires is a healthy dose of sunshine and moist, well-drained soil. Its flowers make fabulous arrangements combined with fern leaves, goldenrod, statice and carnations for example.
Good to know: Before flowering, sunflowers famously optimize their growth by following the course of the sun in a phenomenon known as heliotropism. All summer long, sunflowers attract pollinating insects and butterflies into the garden, improving its ecosystem and encouraging fruit set in the orchard or vegetable patch. The oil-rich seeds are a favourite with garden birds (nuthatches, tits, finches, sparrows, blackbirds etc.). Harvest them after flowering to provide birds with a valuable food source during the cold winter months.
Cooking with sunflowers:
Sunflower buds, petals and seeds are all edible. Brighten up green salads with a few nutty-flavoured petals. The green buds have a Jerusalem artichoke taste when blanched and tossed in garlic butter. Unhulled seeds can be eaten both raw and grilled.

Planting and care
Sow Sunflower 'Claret' F1 from March to May in pots. Use a good quality soil that you will sift on the surface to bind the seed to its substrate. Before sowing, lightly press the soil with a board. Sow your seeds by broadcasting. Cover the seeds by sprinkling soil on top or by using vermiculite, lightly press and water generously with a fine rain. Place your pots in light, without direct sunlight, at a temperature of 20°C to 25°C. Lower the temperature at night to 17°C to create a beneficial alternation for germination.
The seeds will germinate in 21 days. Keep the soil moist but not excessive during growth. 15 days before their final placement, start gradually acclimatising them to a temperature of 15°C.
By the end of May or early June, the temperature will be warm enough in the garden to plant your young plants. Choose a sunny location. Add a good shovelful of compost to each planting hole. Space your plants 45 to 60cm (23.6in) apart.
Seeds sown in May can be directly sown in place. By staggering your sowings, you will extend flowering until autumn. It takes 12 to 14 weeks between sowing and flowering.
Protect your seedlings from attacks by snails and slugs, which are fond of these young plants. By sowing chives near your sunflowers, you will keep aphids away from them.

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).
