Chelsea in Bloom 2027: the free flower show on the street

While the Chelsea Flower Show charges to get in and sells out, the streets outside put on their own show for nothing. Around a hundred and fifty shops, restaurants and hotels between Sloane Square and the King’s Road build large floral installations across their frontages, and you walk round them at whatever pace you like.

It bills itself as the largest free flower festival in London, and on volume of flowers per street that is hard to argue with.

When it runs

The 2027 dates are not announced yet. It wraps the Chelsea Flower Show week every year, and the Flower Show is confirmed for 18 to 22 May 2027, so expect roughly 17 to 23 May. The 2026 edition ran 18 to 24 May. Treat the window on this page as the usual pattern rather than a confirmed date, and check the organisers before you plan a trip around it.

Where to walk

Start at Sloane Square and work up Sloane Street, or come in at Knightsbridge and walk down. The King’s Road carries the rest. The displays are outdoors and permanent for the week, so there is no opening time to miss and nothing to book.

When to go

Early morning if you want photographs without people in them, because by mid afternoon on the Saturday the pavements outside the better known installations are three deep. Weekday mornings are the quiet version. The flowers are at their best in the first half of the week: by the closing weekend the heat and the handling have taken a toll on the more delicate builds.

The paid one

The Chelsea Flower Show itself is ten minutes away at the Royal Hospital, on for the same week, and needs a ticket. We have written that up separately, including which days are members only.
