Housed inside the old St Mary-at-Lambeth church, which is where early gardener and plant hunter John Tradescant is buried, the Garden Museum is tells the story of British gardening from the 16th century to today. The museum’s collection includes gardening tools and artefacts as well as art, photography and painting, and it’s also home to the Archive of Garden Design, which features records from British garden designers from the last two centuries. You can’t very well have a museum dedicated to gardens without one of its own, and it’s a beauty – the courtyard garden, inspired by Tradescant and designed by Dan Pearson, it’s an eden of rare plants. The museum also boasts an excellent cafe, so it really is a place to make a day of it.
