Helianthus annuus. Plant a patch of these beautiful sunflowers and stand back. Flowers are soft yellow, rubber-duck yellow, copper, bronze, terra cotta, chocolate, deep red and a few two-tone striped ones. There are all kinds of shapes and sizes as well, from massive 30-40 cm heads full of black seed to smaller multi-branching heads full of striped seed. Great fun for kids, beautiful cutting flowers and food for the birds if you leave them to go to seed.
