Mongolian Giant Sunflower

This sunflower is huge! It soars as high as 14ft (4.3m), topped by massive flower heads 16-18in (40-45cm) across. It is hard to contemplate seeds sprouting and growing to such nose-bleed heights in just one season! Even the seeds get big, about 1.5in (4cm) long, and they are edible just like "normal" sunflowers. If you have the room, this is a fun plant to grow. 90 days.
