Sunflowers (Helianthus)
Fast-growing, joyful, and towering summer annuals.
Overview
Fast-growing, joyful, and towering, sunflowers are the ultimate quintessential summer annual. They are perfect for introducing young children to the magic of gardening because their rapid, dramatic growth from seed to giant bloom is highly visible and deeply satisfying. Beyond their cheerful, iconic appearance, they play a vital ecological role by producing nutrient-dense seeds for local bird populations and abundant pollen for native bees. Young plants uniquely track the sun across the sky and require sturdy, deep taproots to support their massive, heavy flower heads. These effortless flowers are suitable for any beginner with a sunny patch of soil.
Care Instructions
- Light: Full, direct sun. They literally track the sun across the sky (heliotropism) when young.
- Water: Moderate. Provide deep watering when the soil dries out to encourage deep root growth.
Beginner Note
If growing giant varieties in a breezy location, loosely stake the main stem early on to prevent heavy summer winds from snapping the plant. If you want to save the seeds or use the heads in dried arrangements, cover the maturing head with a paper bag to protect it from birds.
