In the 1930s, Edward Swain, a scholar and one of Australia’s first conservationists, published Eucalyptusdom, a book about the gum tree endemic to Australia. Taking its name from that text, a new exhibition puts the spotlight on the Australian eucalyptus and its shifting symbolism in the country. On display are 400 works from Powerhouse’s permanent collection, all rooted in the eucalyptus. There are delicate pastel vases inspired by the tree, mid-19th-century illustrations of it, ornate 20th-century dining chairs made from it. Seventeen commissioned works—in mediums from film to fashion—also honor the eucalyptus tree. —J.D.
