I was only able to buy a single packet of seeds, it was the last one available. 18 seeds is not many, only 9 germinated, so I am quite dissatisfied.

Description

Helianthus annuus 'Kong F1' is a giant variety that is multi-branching. It features numerous golden yellow, pollen-free blooms on incredible 4.50-metre-tall plants. Ideal for planting in front of unsightly walls or garden sheds. 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. 'Kong F1' is a spectacular hybrid selection that rapidly grows to a height of 4.5m. This multi-stemmed variety plenty of flowerheads (capitulum) per plant, each measuring between 15 and 30cm across (some even reach 60cm). The external petals (technically, ray flowers) are bright golden yellow, arranged around a light 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

Sunflowers can be sown: either in March-April, in pots under shelters, to prepare young plants that can be planted in your flower beds after the last frost. Or from April to June, after the frost, directly in place. In a sunny spot in your garden. In order to enjoy beautiful fresh flowers throughout the season, we advise you to stagger your sowings as much as possible. 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 weaker shoot and keep only one per location. To promote branching of the main stem, you can cut the terminal bud when the plant has developed its fifth leaf. The strong growth of the Sunflower will require regular watering. When the plant reaches about 2.50 m (6.6 ft), watering can be stopped and it can rely on rainfall even if it is scarce. It takes 60 to 90 days between sowing and flowering. Protect your seedlings from attacks by snails and slugs, which are fond of these young plants.
