Description
Helianthus annuus 'Valentine' is wonderful variety that features pale yellow blooms on bushy, well-branched plants. Pollen-free, ideal for cutting! Sunflowers are popular annuals that are generally direct sown in spring in ordinary, well-drained garden soil.
The 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. 'Valentine' rapidly grows to a height of 1.50 m. It produces several flowerheads (capitulum) per stem, each measuring about 15 cm across. The external petals (technically, ray flowers) are pale lemon yellow, arranged around a very dark brown central disc. The flowering period lasts from July to September. The floral stems are strong and well-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 and summer bedding schemes. 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
The Sunflower can be sown:
- either in March-April, in pots under shelter, to prepare young plants that can be planted in your flower beds after the last frost.
- Or from May to June, after the frost, directly in place. In a sunny spot in your garden. To enjoy beautiful fresh flowers throughout the season, we recommend staggering your sowings as much as possible.
Sow Sunflower seeds from March to April in pots. Sow your seeds in groups of 2 at a depth of 1 cm. Use good quality soil that you will sift on the surface to bind the seed to its substrate. Before sowing, lightly press down the soil with a board. Cover the seeds by sprinkling soil or vermiculite on top, lightly press down and water generously with a fine rain. Place your pots in a well-lit area, 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 take 21 days to germinate. Keep the soil moist but not excessively during growth.
20 days after the appearance of the young plants, remove the weaker shoot to keep only one per pot.
15 days before their final planting, start gradually acclimatizing them to a temperature of 15°C. By the end of May or early June, the temperature in the garden will be warm enough to plant your young plants. Choose a sunny location. Add a good shovel of compost to each planting hole. Space your plants 30 cm apart.
The rapid growth of the Sunflower will require regular watering. Once the plant reaches about 100 cm, watering can be stopped and it can rely on rainwater, even if it is scarce.
It takes 84 to 98 days from sowing to 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).
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.
