Petal passion, super-surreal Polaroids and Billy Childish’s California – the week in art

This week’s art roundup highlights several major exhibitions across the UK, including a floral-themed survey at Kettle’s Yard featuring artists from Henri Rousseau to Lubaina Himid. Other notable openings include Billy Childish’s expressionistic California desert paintings at Carl Freedman Gallery, Katharina Grosse’s site-specific installations at White Cube, and Steve McQueen’s new photography book, 'Bounty', which explores the colonial history of Grenada through its flora.

American Rousseaus Return to Paris

Les Rousseau américains de retour à Paris

The Musée de l’Orangerie in Paris is hosting a landmark exhibition titled "Henri Rousseau, l’ambition de la peinture," featuring 50 works by the self-taught master. The show is distinguished by a historic loan from the Barnes Foundation in Philadelphia, which has sent nine paintings to France for the first time since they were acquired a century ago by Albert Barnes. A highlight of the exhibition is the rare gathering of three "manifesto paintings"—The Sleeping Gypsy, Unpleasant Surprise, and The Snake Charmer—displayed together in a dedicated gallery.
