Sunflower 'Russian Giant'
Helianthus annuus Sunflower 'Russian Giant' is indeed a giant among annuals. Give them plenty of room and you will be rewarded with plants up to 3m (10ft) tall with huge yellow flowers often 30cm (12in) in diameter. Useful to grow against an unsightly shed or fence. Birds love the seeds, so grow a few plants close to the house and watch them feed in the autumn. Flowers in the summer. Height 8-10ft.
