The Mongarlowe mallee, also known as the 'ice age gum', may be Australia's loneliest tree. Since its discovery in 1985, extensive searching has revealed the existence of just six trees from four sites.
golden wattle (Acacia pycnantha), which adorns Australia's coat of arms and is currently in bloom.
They are commonly known as golden wattle, Acacia pycnantha is one of the most popular and beautiful trees in Australia. Australia's national floral emblem is Acacia pycnantha, the golden wattle.
There are all sorts of native trees in Australia, from ones with flowers to ones with fruit. You can have fast-growing plants, or ones that take their time. From gum trees to lemon-scented myrtle to the iconic wattle, you're spoiled for choice on what tree to plant.
The Wollemi pine clones itself, forming exact genetic copies. It was thought to be extinct until a tiny remnant population was discovered in Wollemi National Park in 1994. The trunk of the oldest above-ground component, known as the Bill Tree, is about 400-450 years old.
Most of the Gondwanan forests were gone by 2 million years ago, but there remain some isolated remnants. These include the cool temperate rainforests of eastern Australia, from Tasmania to the high mountains of New South Wales and Queensland.
The world's rarest tree is Pennantia baylisiana, also called Three Kings Kaikomako. It was near extinction because the only remaining specimen was female and could not reproduce. However, botanists found viable fruits and planted them within botanical gardens around the world to save it.
Handroanthus spp 'Pink Trumpet Tree' 'Tabebuia'
The pink trumpet tree is planted widely in some regions as street trees because of their hardiness and beautiful pink clusters of trumpet shaped flowers. In these tough growing locations they tend to be smaller in height but will grow anywhere from 6 to 12m.
About the golden wattle
The golden wattle (Acacia pycnantha Benth.) is an evergreen, spreading shrub or small tree. It grows in the under storey of open forest, woodland and in open scrub in South Australia, Victoria, New South Wales and the Australian Capital Territory.
The River Red Gum is widespread across Australia and provides shade along inland waterways, like the Murray-Darling catchment. Forests of this tree contain many significant Aboriginal sites, including trees showing scars where bark was removed to make canoes and shields.
Officially, the oldest tree on Earth is Methuselah, a bristlecone pine of the species Pinus longaeva in the Inyo National Forest of California that is at least 4,789 years old, according to the U.S. Department of Agriculture.
The Jacaranda is undoubtedly the most commonly sighted purple flowering tree in Australia. An attractive purple haze appears across the country every spring as jacaranda trees bloom into colour. Jacaranda trees are part of the family Bignoniaceae and boast long-lasting flowers in stunning shades of light purple.
Hobart is the highest ranking capital city in terms of the proportion of tree canopy to other kinds of ground cover. Hobart boasts 59% tree canopy cover. By comparison, Adelaide has the lowest proportion of tree canopy among Australia's capitals with 27%.
The Cazneaux Tree, also known as Cazneaux's Tree, is a Eucalyptus camaldulensis or river red gum that was made famous by the photographer Harold Cazneaux. It is in the Australian state of South Australia in the locality of Flinders Ranges near Wilpena Pound.
Though the genus Acacia has over a thousand species across the world (commonly known as “wattle”) which range from shrubs to shade trees, the umbrella thorn acacia (Vachellia tortilis), makes a case for being the “smartest” of them all.
Methuselah is a 4,854-year-old Great Basin bristlecone pine (Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California.
Some trees can live for centuries or even millennia but the secrets behind their long life spans have eluded scientists. However, new research has found that the ginkgo tree, which can live more than 1,000 years, doesn't really show any expected effects of aging — they appear to be primed for immortality.
Rainforests covered most of Australia for much of the 40 million years after its separation from Gondwana. However, these rainforests contracted as climatic conditions changed and the continent drifted northwards.
The Rainforest native forest type is found in the Northern Territory and all states except South Australia (Map 1). Two million hectares (55 per cent) are in Queensland and 0.7 million hectares (20 per cent) are in Tasmania. Australia has many types of rainforest, varying with rainfall and latitude.
The Daintree Rainforest is at least 135 million years old – possibly even as old as 180 million years! It is the world's oldest tropical lowland rainforest.
