Lush public domains and native botanical sanctuaries in Oceania
Oceania's garden culture is shaped by isolation and biodiversity. Many of the plants growing in botanical collections here are found nowhere else in the world, and several of the institutions on this page were founded specifically to document and preserve them. Australia and New Zealand both developed colonial-era botanic gardens in the 19th century that have matured into serious scientific institutions, while also functioning as well-used public parks.
The range across the region reflects how different the climates are. Cool temperate gardens in Dunedin and Hobart grow things that wouldn't survive in tropical Queensland, and the highland gardens of the Blue Mountains operate in conditions closer to northern Europe than to coastal Sydney. Some of the most interesting plant collections are in places that don't advertise themselves as garden destinations at all.
Native flora is a recurring theme in a way that sets Oceania apart from other regions. Australian wildflowers, New Zealand ferns and forest trees, Pacific island endemics. A lot of what's worth seeing here isn't ornamental planting in the European sense but ecosystems that happen to be accessible. That shifts what you're looking for and makes timing and location matter in different ways than they do elsewhere.
Adelaide Botanic Garden's Bicentennial Conservatory shelters a slice of rainforest under one long glass roof. Inside, a giant Amazon water lily can spread its pads wide enough to hold a small child. Visitors can wander the Palm House, one of the oldest glasshouses in Australia. A Museum of Economic Botany from 1881 stands nearby.
One Tree Hill rises from Cornwall Park, an old volcanic cone south of the city centre. Maori built terraced pa fortifications into its slopes centuries before Europeans arrived. Visitors can walk grazing paddocks past sheep and old stone walls. The summit obelisk marks the grave of the park's donor.
The Royal Botanic Gardens Victoria in Melbourne were laid out along the Yarra River in 1846. Baron Ferdinand von Mueller shaped much of the collection during his time as director. Visitors can walk past a large ornamental lake ringed by weeping willows. A separate garden at Cranbourne grows only Australian native plants.
Christchurch Botanic Gardens were founded in 1863 with a single oak tree planted for a royal wedding. The Avon River loops around the gardens through punting boats and willow trees. Visitors can walk from rose beds into a fernery and rock garden. Hagley Park surrounds the gardens with open lawns and cricket grounds.
Mount Tomah Botanic Garden sits over 1,000 metres up in the Blue Mountains west of Sydney. Cool climate plants from around the world grow here instead of native eucalyptus. Visitors can walk paths overlooking the Grose Valley wilderness below. Frost and occasional snow shape what can survive in these beds.
The Australian National Botanic Garden grows only native Australian species across its hillside site. Its Red Centre Garden recreates the look of the outback with desert plants and red gravel. Visitors can follow a rainforest gully trail shaded by tree ferns. The garden sits on the slopes of Black Mountain above the city.
Auckland Domain fills the crater and slopes of the extinct Pukekawa volcano. Its Wintergardens hold two glasshouses of ferns, orchids and tropical plants. Visitors can walk shaded paths past duck ponds and open sports fields. The Auckland War Memorial Museum stands on the highest point of the park.
Kings Park covers around 400 hectares on a ridge overlooking the Swan River and city skyline. Each spring its wildflower displays draw crowds during Kings Park Festival. Visitors can walk a treetop glass bridge suspended among eucalyptus canopies. A war memorial and eternal flame stand near the main lookout.
The Royal Tasmanian Botanical Gardens opened in 1818, making them Australia's second oldest botanic garden. A Japanese garden and a subantarctic plant house sit within the walled grounds. Visitors can walk past a conservatory built from an old convict built wall. The Derwent River is visible from several points along the paths.
A cable car climbs from downtown Wellington straight into the botanic garden at the top. Norwood Cottage and a begonia house sit among winding paths and native bush. Visitors can walk down through rose beds towards the lake at the bottom gate. The Carter Observatory shares the same hilltop grounds.
Government Gardens in Rotorua surround the ornate Tudor style Bath House built in 1908. Steam rises from geothermal vents scattered through the manicured lawns. Visitors can walk past rose gardens and a lawn bowls green beside the lake. The old Blue Baths pavilion still stands a short walk from the gardens.
Kentia palms grow wild across Lord Howe Island and were once its main export crop. Forest still covers much of the island beneath the twin peaks of Mount Gower. Visitors can walk trails through palm groves found nowhere else on Earth. Seedlings are still harvested here and shipped worldwide as house plants.
Norfolk Island pines tower over the island's national park in the interior highlands. Captain Cook noted the tall, straight trees when he landed here in 1774. Visitors can walk rainforest trails past the endangered Norfolk Island parakeet. Moss covered banyan trees line some of the older forest paths.
The Flecker Garden inside Cairns Botanic Gardens grows tropical plants beside a lowland rainforest boardwalk. Timber walkways lead through the swamp forest without disturbing the roots below. Visitors can spot orchids, palms and cycads collected from across the wet tropics. A saltwater lake nearby draws herons and other wading birds.
The Royal Botanic Garden Sydney was founded in 1816 on the edge of the harbour. A rare Wollemi pine, thought extinct until 1994, grows behind locked gates here. Visitors can follow the harbourside path towards the Opera House and bridge. Flying foxes once roosted in the fig trees above the main lawn.
