About the sunflower
Sunflowers are native to North America and were cultivated by Indigenous peoples for their edible seeds and oil. Young plants show heliotropism, tracking the sun across the sky each day, though mature flower heads usually settle facing east. Beyond the giant single-stem types, there are branching and dwarf varieties in gold, orange, red, and cream.

Sunflower FAQs
Do sunflowers really follow the sun?
Young sunflowers do — a behavior called heliotropism — turning to track the sun across the sky. Once the flower head matures, it usually stops and faces east.
How tall do sunflowers grow?
It depends on the variety: dwarf types stay under two feet, while giant varieties can reach 12 feet or more in a single season.
When should I plant sunflowers?
Sow sunflower seeds directly in the garden after the last spring frost, once the soil has warmed. They grow quickly and bloom in as little as two to three months.
