The Christchurch Botanic Gardens, located in the central city of Christchurch, New Zealand, were founded in 1863 when an English oak was planted to commemorate the solemnisation of the marriage of Prince Albert and Princess Alexandra of Denmark. In a loop of the Avon River, bordered on three sides by the green expanse of Hagley Park, are the Christchurch Botanic Gardens. With more than one and a half million recorded visits each year, the Gardens are one of the city’s most visited public facilities. The Gardens are at the heart of Christchurch’s reputation as the Garden City. A temperate climate supports many thousands of plants, gathered from around the world and across New Zealand since 1863.
