Sunflower Giant Single Seeds

If normal sunflowers aren’t tall enough for you, our giant sunflower seeds are exactly what your garden needs. Giant Sunflowers (Helianthus annuus) add drama and height to any outdoor space, and are a favourite with children - who can grow the tallest sunflower?

These sunflowers can reach heights of up to 6 feet or more, and their large flower heads follow the sun throughout the day. They are hardy annuals that thrive in well-drained soil with full sun exposure.

Sunflowers are long-lasting, whether used in the garden or as cut flowers, and are great for wildlife. They are fantastic for pollinators and their spent heads can be left to feed birds throughout winter. Even the seeds produced by these sunflowers are a treat: they are perfect for roasting and eating or, again, for the birds. The strong stems of Giant Sunflowers can also be used as natural supports for climbing plants.

Order your Giant Sunflower seeds today and add a touch of natural grandeur to your garden.
