Exhibition Going Dutch in the London Garden Museum, 5 October - 20 February 2011 Henk Gerritsen started designing the Dutch Priona gardens in 1978. He is internationally well-known as the writer of the first Piet Oudolf books and as a designer of gardens in several countries. One of his best projects was a complete renovation of the organic gardens at Waltham Place, near London. Essay on gardening however is not a game between well-matched opponents. Nature is much more powerful than man. Thinking ahead is not sufficient; nature is an unpredictable opponent, who may come forward with moves that no man could have foreseen.
