OSC Sunflower Large Grey Striped Flower Seed Packets


60 Days To Harvest: Huge single yellow blooms ranging from 25-35cm in diameter are produced on tree trunk like stems that can easily reach 3m in height! May require staking due to weight of the seed head.

Sowing: Start seeds outdoors mid-May in sunny site with good drainage. Sow seeds 6-12mm deep and 8-10cm apart. Thin or transplant to 30-45cm apart after germination.

Comments: Best variety for roasting seeds. Birds love it, too!
