Description
As the name suggests this very tall growing variety of Sunflower is fun and easy to grow and children will love them! The flowers are huge and will last all the summer long! Grow them close to a sheltered sunny wall and they will keep flowering until the first frosts. Perfect in a hot sunny garden and attractive to bees. Don’t forget you can eat the ripened seeds so what is there not to like!Direct sow Sunflower seeds outdoors where they are to grow from April to May. Choose a position in full sun on well drained soil which has been raked to a fine tilth. Sow seeds thinly, at a depth of 1cm (1/2") in drills spaced 45cm (18") apart and cover seed with its own depth of soil to exclude light. Water the ground regularly, especially during dry periods. Germination usually takes up to 21 days. When sunflower seedlings are large enough to handle, thin them out to 45cm (18") apart.Alternatively, sow indoors in individual 7.5cm (3") pots from March to April at a temperature of 20-25C (68-77F). Once germinated, grow sunflower plants on in cooler conditions until large enough to plant outdoors after all risk of frost has passed. Prefers a well-drained soil in full sun.Product Specifications:. Position: Full sun. Height: Up to 450cm (177in/11-15ft) when fully established. Spread: Up to 45cm (18in) when fully established.
