American Giant is a super tall hybrid sunflower growing between 8 and 15 feet tall, making it perfect for gardeners wanting the tallest sunflower in the neighborhood. Its sturdy stature reduces the risk of falling over in wind or rain compared to other giant types.
This sunflower also serves as an excellent windbreak along hedgerows or property perimeters. Additionally, leaving the flower heads on allows for seed production that attracts birds later in the season, adding wildlife value to your garden.
