Super Giant Sunflower 10 seeds

Helianthus Craven Strain, a huge, heavy 4" diameter stemmed sunflower with large very heavy flower heads 18” across and big leaves, capable of achieving 20ft or more with a rich soil and an early sowing. The original seed source came from a 25ft record height sunflower.  They need an early start and a long growing season to develop their full potential and some support will be needed in early autumn as windy conditions set in.
