Rooms go quieter when deep green is this sure of itself. The leaves are cropped close and lit from behind, with pale blue and coral patches breaking up all that green and a low band of pink dahlias and daisies at the base. Hung up, it does the job a window onto a garden does the wall stops feeling flat and the room gains depth. Best on a full wall above a sofa or sideboard, in a hallway, or on a stair landing where you pass it often. Pair it with linen, cane, dark timber and cream stoneware, and let one or two plants echo it rather than a whole shelf. Skip busy patterned wallpaper beside it; this piece is the pattern. On paper the colour edges stay crisp and the pale patches keep their light.
