RHS Chelsea Flower Show in London
Held on the grounds of the Royal Hospital Chelsea since 1913, the RHS Chelsea Flower Show pairs elaborate, purpose-built show gardens judged for medals with the Great Pavilion's enormous floral marquee of prize specimens, drawing royal visitors and serious horticulturists alike to what remains the world's most prestigious annual competitive garden design event.
The Royal Horticultural Society has staged its flagship flower show on the grounds of the Royal Hospital Chelsea since 1913, turning the historic home of retired soldiers, the Chelsea Pensioners, into the world's most prestigious annual gathering of competitive garden design each May.
