The gardens of the entire world summarized and consolidated into one place in several greenhouses, outdoor parks, and orchards!
A fairly easy drive from London, a couple of minutes, parking is accessible and cheap. The entrance of the gardens cost about 15 Pound. But its worth it, trust me. The gardens feature so many things, from tropical to semi-arid, to the many flowers of the world. The restaurant / cafe features some of the U.Ks finest pastries too.
