We like art nouveau florals best when they come with a little abrasion. This one trades the tidy nosegay for a swarm of glowing blooms drifting up a near-black, deep blue ground. Put it up and a quiet room finds a centre of gravity. The dark field swallows clutter, and the gold, white and cobalt dots act almost like lamplight on a wall. Best above a bed, a desk, or a sideboard in a room you actually sit in after dark bedrooms, studies, dining rooms. Pair it with deep greens, navy, oat linen, dark oak and a bit of brass. Don’t crowd it with other busy florals or pastel art nearby; let it carry the wall on its own. Stretched canvas reads soft and painterly under low light.
