Laid out in 1842, the lush Trädgårdsföreningen is a large protected area off Nya Allén. Full of flowers and tiny cafes, it’s popular for lunchtime escapes and is home to Europe’s largest rosarium , with around 2500 varieties. The gracious 19th-century Palmhuset (open 10am to 8pm) is a bite-size version of the Crystal Palace in London, with five differently heated halls: look out for the impressive camellia collection and the 2m-wide tropical lily pads.
