SUNFLOWER – Giant Russian (10 Seeds)

Helianthus annuus

Organically grown by us  – A selected variety which has uniform large black seeds and very large 40cm brilliant golden heads, plant is approx. 1.5m tall, the seed is high in protein very tasty nutty flavours, can be used to provide all year round supply of food for birds, guinea pigs and rabbits etc. Giant more by head size rather than by height.  Please see Mammoth Sunflowers if you prefer the really tall ones.

  • Height: 150cm
  • Flower heads: Multiple heads, one large then gradually smaller
  • Germination: 3-7 days, temp above 18oC
  • Sowing: 1cm deep. Start in pots or direct in ground (if snails and birds are not an issue)
  • Spacing: 50 – 70cm apart
  • Soil fertility: Rich compost filled, well-draining soil. Sunflowers have a high potassium requirement and ensure your soil is not boron deficient.

Growing Tips: Water deeply occasionally rather than regular short sprinkles.  Concentrate water towards the base of the plant rather than the leaves to avoid rotting stem. Add plenty of blood n bone and compost when planting.
