Sunflower 'Mongolian Giant'

'Mongolian Giant' sunflower has the largest edible seeds of any variety we've ever grown. It also has the largest flower heads, measuring 12-18 inches. Our plants were so top-heavy they had to be propped up near the end of the season to keep them from blowing over.

The seedheads mature in 90-100 days.
