In 1875 Morris began his revolutionary experiments with vegetable dyes, which in 1881 resulted in its most delicate printed and woven fabrics, carpets, and tapestries.
Registered in May 1883, this fabric was named after the blackbirds who stole strawberries from the garden at the Kelmscott Estate. It was an expensive fabric to produce, incorporating sophisticated dyeing techniques, and proved one of the most commercially successful designs.
Morris wallpaper design is based on plant forms, whether in a luxurious naturalistic style (for example, "Acanthus" or "Pimpernel") or a flatter and more formalized (for example, "Sunflower" or "St. James Ceiling"). During his career, he has released more than 50 wallpaper designs.
