This year we are launching possibly the worlds tallest sunflower ever produced. British-bred for British conditions! Height 5.2m (17'). While the vibrant, ever-popular sunflower is widely recognised for its beauty, it's also an important source of food. That's why.. .. We're celebrating the SUNFLOWER. Easy to grow & a real favourite with children. Flowers like very large daisies with brightly coloured petals. Pollen-free varieties are ideal for hayfever sufferers & for cutting. Use petals & seeds in salads & cakes.
