This is a cultivar of the true North American native that is such a familiar sight. This sunflower traveled to Europe where it was further cultivated into this giant. Great for large seeds and decorative heads. Thin seedlings to 2' - 3' apart. These may need support against a wall or fence in windy areas and will do better if planted with composted manure and slow release fertilizer.
