Sunflowers are among the easiest flowers to grow from seed. They attract pollinators, provide edible seeds, and make spectacular cut flowers. Giants can reach 12+ feet with dinner-plate-sized heads.
Sunflowers grow as annuals in all zones. Extremely adaptable — from Zone 2 to 11. Just need warm soil (60°F+) and direct sunlight.
How to Grow Sunflower: Step-by-Step
- Direct sow after last frost — sunflowers don't love transplanting
- Plant in full sun; they literally follow the sun (heliotropism)
- Water young plants regularly; established plants tolerate drought
- Stake giant varieties once plants reach 3+ feet
- Harvest seeds when back of head turns brown and seeds feel firm
