When Canberra was being planned in the 1930s, the establishment of the gardens was recommended in a report in 1933 by the
Australian Capital Territory Advisory Council. In 1935, The Dickson Report set forth a framework for their development. A large site for the gardens was set aside on
Black Mountain. In September 1949, the ceremonial planting of the first
trees by Prime Minister
Ben Chifley and Sir Edward Salisbury, director of
Kew Gardens, took place. Development of the site, facilities and collection progressed and the Gardens were officially opened in October 1970 by Prime Minister
John Gorton. To celebrate the Gardens' 50th anniversary in 2020, a new
Banksia garden was added, showcasing a wide selection of the over-170
Banksia species spread across the coasts and hinterland of most of mainland Australia and Tasmania. The Gardens has tenure over on Black Mountain. Approximately are currently developed as the Botanic Gardens. Plans for the development of the remaining land are on hold until funds are available. ==Collection==
