Single-flower

■ Sunflower, tall yellow.
■ Anyone who has ever travelled through French Burgundy knows the summer fields full of 'tournesol', golden-yellow sunflowers, shining like the sun itself.
■ The originally tallest species is the giganteus.
■ It stands out in particular along walls and fences or as a solitary, but with support.
■ Mind the snails.
■ The dried seeds are a treat for birds in winter.
