Chelsea in Bloom 2026 returns with this year’s theme, “Out of this World,” transforming Chelsea into a cosmic floral wonderland inspired by space travel, astrology and spiritual symbolism.
Visitors can explore six large-scale floral installations across the neighbourhood, including a zodiac-inspired constellation in Sloane Square, a UFO above Pavilion Road, a lunar landscape at Duke of York Square, and mythical floral sculptures along Sloane Street. On King’s Road, a giant floral globe celebrates the 100th birthday of David Attenborough.
