Plant Theory Giant Single Sunflower Seeds

Our helianthus annuus Giant Sunflower single seeds are a fun favourite with children. Easy and quick to grow with huge heads on giant stems, they make for a fun competition to see who can grow the tallest sunflower. Sunflowers add warmth and vibrancy to any outdoors space, and attract a wealth of bees, butterflies, and other beneficial insects to your garden. The spent heads can also be used to feed birds during the winter.
