Ultimate Guide to 17 Best Botanical Gardens in London
London might be famous for its busy streets, historic landmarks and endless restaurants, but the capital is also home to an impressive collection of gardens where plants take centre stage.
From world-famous botanical collections and enormous glasshouses to peaceful community gardens and specialist plant spaces, these green destinations offer a completely different side of London. They are places to discover rare plants, wander through themed landscapes, admire seasonal flowers, or simply escape the noise of the city for a few hours.
Some are perfect for serious plant lovers, while others are better suited to a relaxed weekend walk, photography session or family day out.

Beyond the plants, Kew also offers architectural landmarks, tree-top walks, museums and seasonal events.
