Later this month, London’s largest free flower show opens to the public, filling streets across Belgravia and Chelsea with decorative displays to delight the eye.

A free tie-in with the paid-for Chelsea Flower Show, Chelsea in Bloom, and its Belgravia partner offers local residents and businesses a chance to showcase some often remarkably ornate decorative displays. And the whole lot is free to see.

Mostly created for the many posh boutiques that fill the streets of this part of London, they range from small window displays to huge confections that spill over the streets.
Each year is themed, and for Chelsea it’s Out of this world, while Belgravia is going for Fairy Tales of Belgravia with installations reflecting spring, summer, autumn and winter.
The displays run from Monday 18th May 2026 to Sunday 24th May 2026 and are all free to visit.

More venues participate in the Chelsea display, which tends to be more compact, filling the main streets around Sloane Square, whereas Belgravia’s display is more scattered around the streets. My tip is to get the maps off both websites, but start with Chelsea as it’s easier to see more with less walking, and then wander over to Belgravia afterwards.
You could add a third event if you visit on Saturday 23rd May in the late afternoon, as that’s when the Chelsea Flower Show closes, and at 4pm, many of the plants and flowers are sold to the attendees inside. So, head to Chelsea Bridge Road from about 4pm onwards to see hundreds of people staggering up the road laden with huge bundles of flowers.
Looks a bit like a floral conclusion to Macbeth.
