London’s Royal Parks are among its most beautiful and beloved spaces: just as much as the Houses of Parliament, Buckingham Palace or St Pancras Station, the mere mention of Hyde Park or Greenwich Park is enough to evoke the capital in all its glory for residents and tourists alike. They have a magnificent history – some were royally owned as far back as the Norman conquest, others were acquired by Henry VIII during the Reformation and were great hunting grounds for successive monarchs – and since being opened to the public, they have hosted some of London’s great events, including the Great Exhibition in Hyde Park and innumerable jubilees, international games and competitions and celebrations. Today, the Royal Parks are visited by over 77 million visitors. But what are the ingredients of these magnificent green spaces? We often think of wider landscapes of trees, grass, lakes, meandering footways, bedding displays and herbaceous borders. But the Royal Parks are much more than this.
