About sunflower 'giant single'

Sunflower 'Giant Single' is a tall-growing, single stemmed variety of the traditional easy-to-grow sunflower. The blooms have dark centres and attractive bright golden petals, held on tall stems which are capable of growing several metres.
Like most annuals, they are extremely useful in the border, filling gaps between young shrubs and perennials with immediate explosions of colour and height. It is an ideal variety for mass planting or for children to grow. if planted next to a wall or tall cane they can chart its progress as it grows.
