There are an estimated 20,000-21,000 species of native Australian flowering plants
Australia is home to a diverse range of native flowering plants, with estimates placing the total number of species between 20,000 and 21,000 or possibly slightly higher. This includes a wide array of shrubs, bushes, trees, and grasses that can be found in various habitats across the country, from the rainforests of New South Wales and Queensland to the arid and savanna grassland areas of Western Australia.
The exact number of native flowering plant species in Australia has been a subject of discussion, with estimates varying over time. Some earlier estimates placed the number of species at around 15,000 to 18,000. However, more recent analyses suggest a higher figure, with one report from 2009 providing an estimate of 18,448 native species on the Australian mainland and 18,706 when including offshore islands.
Among the vast array of Australian native flowering plants, several iconic species stand out. The waratah, with its bright red flowers, is the NSW State floral emblem and was even a contender to become Australia's national emblem in the 1900s. Another well-known plant is the Banksia, with its distinctive chunky, cylindrical flowers. There are over 100 Banksia species, most of which are found in Western Australia, and they play a crucial role in providing food for animals and small mammals.
In addition to these, Australia boasts a variety of other unique flowering plants. The Illawarra flame tree, with its invasive root system, grows in subtropical rainforests, while the silky oak, the tallest grevillea, can reach heights of up to 30 meters and bears spectacular golden flowers in spring. The golden wattle, the lily pilly, and the hop bush are also notable native Australian flowering plants, each with its own distinct characteristics and ecological significance.

The iconic golden wattle is a native Australian flower
The iconic golden wattle, also known as Acacia pycnantha, is a native Australian flower. It is Australia's national floral emblem and has been a culturally important plant for Aboriginal people for thousands of years. Wattle is found in every state and territory of Australia and is a remnant Gondwanaland species that has been in the country for 35 million years. The golden wattle is native to south-eastern Australia, where it grows as an understorey plant in eucalyptus forests. It is a tree of the family Fabaceae, growing to a height of 8 metres and possessing a unique structure with phyllodes (flattened leaf stalks) instead of true leaves.
The golden wattle typically flowers from July to November, with fragrant, golden blooms that are used in perfume-making and honey production. The flower heads are ball-like structures covered by 40 to 80 small flowers with five tiny petals and long erect stamens, giving the flower a fluffy appearance. Wattle comes in many shapes and sizes, from groundcovers to large trees, and is a popular addition to gardens across Australia.
The golden wattle holds significant cultural and historical value for Australians. It is believed to be the country's only authentic national symbol, with its green and gold colours inspiring Australia's national colours. Wattle has been featured on various national honours, including medals and awards, and was even worn by soldiers during World War I as a reminder of home. The first use of wattle as a symbol of Australia dates back to 1838 in Hobart, Tasmania, and Wattle Day on the first day of spring has been a national day of celebration since the early 1900s.
In addition to its cultural significance, the golden wattle has practical applications. Its bark produces the highest yield of tannin among wattle species, leading to its commercial cultivation for tannin production. The scented flowers are used in perfume-making, and the plant has been grown in temperate regions worldwide for this purpose. The gum produced by the golden wattle has also been explored as a possible alternative to gum arabic in the food industry.

The Illawarra flame tree is a native Australian tree that flowers in the spring and summer
Australia is home to a wide variety of native flowers, from blooming wildflowers to Eucalyptus trees. The country boasts over 12,000 species of wildflower in Western Australia alone.
One of the most iconic flowering trees in Australia is the Illawarra flame tree. With its bright red bell-shaped flowers, the Illawarra flame tree (Brachychiton acerifolius) is a native Australian tree that flowers in the spring and summer. It is a deciduous tree, losing its leaves during the dry season before flowering. The Illawarra flame tree grows in subtropical rainforests in New South Wales and Queensland, reaching up to 35 metres in the wild and about 10 metres in gardens.
The Illawarra flame tree is easily recognisable for its distinctive appearance. The bright red flowers grow in clusters at the end of branches, often after the leaves have dropped, creating a striking contrast. The flowers are slow to appear, taking around 8-10 years to bloom, but the wait is rewarded with an explosion of fiery coral red blooms. The tree produces large dark brown seed pods containing rows of corn-like seeds surrounded by hairs. These seeds are toxic to many native animals and birds, but the tree still supports a wide range of wildlife, providing food and habitat.
The Illawarra flame tree is a popular choice for larger gardens, offering both beauty and shade. It is well-suited to the local climate and environment, tolerating light frost once established and thriving in most soil types, including clay. The tree is also a source of cultural significance, with Aboriginal Australians historically using the inner bark for making string, fishing nets, and traps, as well as a food resource.
Overall, the Illawarra flame tree is a spectacular native Australian tree that adds colour and life to the country's landscapes during spring and summer. Its unique characteristics and ecological importance make it a beloved and iconic symbol of Australia's natural beauty.

The banksia is a native Australian flower with a unique, chunky shape
Australia is home to a wide variety of native flowers, from the iconic golden wattle to native pea flowers and spikey hakeas. The exact number of native flowering species in Australia is hard to pin down, but it's clear that the country boasts an impressive floral diversity.
One of these native flowers is the Banksia, a unique and chunky flower that is instantly recognisable. Banksia is a genus of around 170 species of flowering plants in the family Proteaceae. Most Banksia species are found in Western Australia, and they thrive in a variety of landscapes, from sclerophyll forests to rainforests, shrublands, and even some arid regions. They are not found in Australia's deserts, however.
Banksias are characterised by their chunky, cylindrical flower heads with distinctive spikes. These spikes are a key source of nectar for birds, small mammals, and even humans! Banksia nectar is rich and flavourful, attracting bees and other pollinators. Beekeepers often place their hives near Banksia groves to produce a unique and sought-after variety of honey called Banksia honey.
The Indigenous people of southwestern Australia have traditionally used Banksia flowers in a variety of ways. They would suck on the flower spikes to obtain nectar or soak them in water to make a sweet drink. The Noongar people of the same region also used infusions of the flower spikes to relieve coughs and sore throats.
Banksia is a popular choice for gardens and landscapes due to its large, showy flower heads and the fact that it attracts birds and small mammals. Banksia plants can also be cultivated indoors as houseplants. However, banksias are susceptible to dieback, which thrives in moist soil conditions, so they may not be suitable for all environments.

The waratah is a spectacular native Australian flower and the NSW state floral emblem
Australia is home to a wide variety of native flowers, from the iconic golden wattle to the stunning native pea flowers and spikey hakeas. With such a diverse range of flora, it's no surprise that the waratah, a spectacular native Australian flower, has been chosen as the NSW state floral emblem.
The waratah, with its vibrant crimson flower head, is a true icon of the Aussie bush. It is widely recognised as one of the best-known and most beautiful Australian native plants. This distinctive flower, which can grow up to 15cm across, is a cultural symbol that adorns everything from stamps to the state flag of New South Wales. The waratah is native to the east coast of Australia and Tasmania, and its bias towards coastal habitat played a role in its selection as the NSW state floral emblem.
The waratah is not just admired for its beauty; it also holds cultural and historical significance. In Indigenous Dreamtime stories, the wonga pigeon is linked to the waratah. Additionally, the waratah almost became Australia's national emblem in the 1900s, losing out to the golden wattle due to its coastal habitat preference. Despite this, the waratah was officially proclaimed the floral emblem of New South Wales in 1962, solidifying its place as a symbol of the state.
The waratah typically grows in forest understoreys and on sandstone ridges, thriving in the unique Australian environment. It can be found in national parks along the New South Wales coastline, as well as in nearby mountain ranges and on the NSW South Coast. Growing to a maximum height of 4 metres, the waratah is a hardy flowering shrub with dark green, leathery, serrated leaves. It blossoms in spring, adding a bold splash of colour to the landscape.
The waratah is more than just a flower; it is a symbol of NSW, a source of artistic inspiration, and a testament to the beauty and diversity of Australia's native flora. Its selection as the NSW state floral emblem celebrates the waratah's cultural significance and its role in shaping Australia's natural and cultural identity.
