Description
Everyone loves this fast growing sunflower with enormous golden-yellow blossoms and edible seeds. Quickly grows to 8-10′ with minimal care. Very easy to grow. Great for a temporary hedge around the garden. Attracts pollinators. Annual.
Select a location with full to part sun and average soil. May be started indoors four weeks before last frost date. Keep young plants evenly moist and well weeded. Sunflowers are heat and drought tolerant once established, but will grow shorter in harsh conditions. Harvest seeds by hanging mature heads upside down in a cool dry area for a few weeks. The seeds will brush off the flower head when completely dry.
