Sunflower 'Russian Giant' - RHS endorsed seeds for children

Helianthus annuus

Hardy Annual

I could be the tallest flower in your garden. Can you grow the tallest, sunniest sunflower? When I have finished flowering leave the flowerheads out to feed the birds over the winter. Height: 2m+.Did You Know? - Not all sunflowers are yellow or tall. Look for furry-looking teddy bear types, different colours and ones with several flowers on one stem.

These seeds are endorsed by the RHS.


Culinary note: Some parts of these flowers are edible. Try toasting the seed kernels for a healthy snack. For more details about edible flowers click here.


Companion planting: Try growing sunflowers with chives to deter aphids.

Sow me indoors from February to April. Fill some 7.5cm pots almost to the rim with some moist seed compost. Push 3 seeds into the centre of each pot and cover with the compost. Place in a warm place in a light position. Keep the pots well watered until my seedlings appear - about 7 days. Move the plants to a bright windowsill, water regularly until I am well grown.Sow me outdoors from May to early June Choose where you want me to grow. Rake the ground so it is nice and fine and remove any big stones. Sow me 20mm deep and 40cm apart. Make sure the rows are 45-60cm apart.

For indoor sown plants - when all risk of frost has gone, plant me outside somewhere sunny and well-drained.

Measure how tall your sunflowers grow and how big the flower head is.
