Australia's National Flower: The Golden Wattle
You'll find the golden wattle, or Acacia pycnantha, growing in the wild in many parts of Australia, such as in South Australia's Eyre Peninsula, western Victoria and southern inland areas of New South Wales. It typically grows to about 4 to 8 meters (13 to 26 feet).
Acacia is the largest genus in the family Mimosaceae, the Mimosa family, which is mainly tropical and sub-tropical. Mature golden wattle plants are said to be reasonably frost and drought tolerant. The specimen shown above was planted in the Royal Botanic Gardens Sydney in 1987.
Selection Criteria & National Wattle Day
Because native golden wattle grew naturally in the Australian Capital Territory and had other desirable features including design potential, it enjoyed popular acceptance as Australia's national flower. It was proclaimed Australia's national flower in 1988, the year of Australia's bicentenary. In 1992, September 1st was formally declared National Wattle Day.Continue to 2 of 9 below.

Australian Capital Territory: Royal Blue Bell
The royal bluebell, Wahlenbergia gloriosa, is the floral emblem of the Australian Capital Territory. Native occurrence in the region was the main criterion for choosing the floral emblem but other desirable features of the royal bluebell included horticultural merit and design potential, both in naturalistic and stylized representations.
Violet Blue Flowers
Wahlenbergia gloriosa belongs to the Campanulaceae family. It is a small perennial herb with oblong leaves about 2.5 centimeters long. The leaf margins are conspicuously waved.
The violet-blue flowers are up to 2-3 centimeters in diameter and often appear to have a paler center due to the light blue base of the petals combined with the purple style which ends in two white stigmas. The flowers may be erect or nodding and are carried on long slender stems.
A related species belonging to the Campanulaceae family is the great blue lobelia, also known as the cardinal flower.
In the Australian Capital Territory, the royal... bluebell can be found in sub-alpine woodland. It is a legally protected plant throughout its occurrence in the wild.Continue to 3 of 9 below.

New South Wales: Waratah
The waratah, Telopea speciosissima, is the state flower of New South Wales. It belongs to the Proteaceae family which includes the protea or sugarbush.
It is fairly widespread on the Central Coast and nearby mountains, growing mainly in open forest as a shrub up to four meters (13 feet) in height. It also grows and flourishes in gardens.
Deep Red Flowers
The waratah is distinguished by a mass of deep red flowers grouped in rounded heads 7 to 10 centimeters in diameter surrounded by crimson bracts. It was proclaimed the official floral emblem of New South Wales in 1962. The waratah flowers from September to November with nectar-seeking birds acting as pollinators.
Telopea is derived from the Greek telopos, meaning "seen from afar." Speciosissima is the superlative of the Latin speciosus, meaning "beautiful" or "handsome." Waratah is the Aboriginal name for the species.Continue to 4 of 9 below.

Northern Territory: Sturt's Desert Rose
Sturt's desert rose (also known as Sturt desert rose), Gossypium sturtianum, is the floral emblem of Australia's Northern Territory.
The specific and varietal names, sturtianum, honor Australian explorer Captain Charles Sturt (1795-1869) who first collected the species "in the beds of the creeks on the Barrier Range" during his journey to central Australia in 1844-45. Gossypium belongs to the hibiscus family, Malvaceae, which is widespread in tropical and temperate regions of the world. It is related to the cotton plant which also belongs to the Malvaceae family.
According to the Australian National Botanic Gardens, Sturt's desert rose forms a relatively compact shrub about a meter high (3 feet) (but may reach 2 meters, or 6 feet, in cultivation) with dark green round-to-oval leaves usually with black stipples. The flowers have mauve petals about 5 centimeters long with red bases forming a contrasting center.
Sturt's desert rose has also been known as Darling River... rose, cotton rosebush and Australian cotton.
It can be found on stony or rocky slopes, or in dry creek beds, around Alice Springs and in the southern part of the Northern Territory, northeastern South Australia, western Queensland, western New South Wales and parts of northern Western Australia.Continue to 5 of 9 below.

Queensland: Cooktown Orchid
The Cooktown orchid, Dendrobium phalaenopsis, is the state flower of Queensland. Originally thought to be Dendrobium bigibbum, the correct botanical name for the Cooktown orchid has been the subject of speculation and debate.
In fact, when the Cooktown orchid was proclaimed the floral emblem of Queensland in 1959, it was under the botanical name of Dendrobium bigibbum var phalaenopsis. But it appeared that when British botanist John Lindley (1799-1865) named the plant, it was not to be found near Cooktown, the north Queensland town after which the orchid was named.
In 1880, New South Wales Surveyor General Robert FitzGerald described Dendrobium phalaenopsis as "obtained near Cooktown." A color plate of the orchid, which he published in December that year, is said to clearly illustrate the plant now known as the Cooktown orchid which FitzGerald described as "obtained in northern Queensland."
Genus and Species
The generic name Dendrobium comes the Greek dendron (tree) and bios... (life). Many species of this genus are to be found on tree trunks and branches. The specific name phalaenopsis comes from the Greek phalaina (moth). The flower of the Cooktown orchid resembles a moth.
Leaves and Flowers
The Australian National Botanic Gardens describe the plants as "up to 80 centimeters in height, comprising 3 to 20 flowering canes up to 1 1/2 centimeters in diameter. Three to six lance-shaped leaves, 5 to 12 centimeters long, are arranged on the upper parts of the pseudobulbs. The stems bearing the flowers are 10 to 40 centimeters long, carrying up to 20 flowers. Each flower is about 3 to 6 centimeters wide and usually colored deep to pale lilac, or rarely white. It usually flowers in the dry season in the wild, but may flower throughout the year in cultivation."
Where It Grows
The Cooktown orchid is to be found in its natural habitat in northern Queensland, from Johnston River near Innisfail south of Cairns to Iron Range in the Cape York Peninsula.
Although found in tropical districts with very high summer rainfall, the Cooktown orchid is not a rainforest species. It grows in exposed situations usually attached to tree trunks.
The Cooktown orchid may be propagated from seed and grown outdoors as far south as Brisbane attached by wire or twine to the eastern or northern side of a tree. It can also be grown in pots using fern fiber as growing medium.Continue to 6 of 9 below.

South Australia: Sturt's Desert Pea
Sturt's desert pea, Swainsona formosa, is the state flower of South Australia. It was adopted as the state's floral emblem in 1961.
First discovered by the English explorer William Dampier on his 1688 visit to islands off the northwestern Australian coast, the plant's presence was noted by Australian explorer Charles Sturt in 1844 in areas between Adelaide and Central Australia. The flower was named after Sturt to commemorate his exploration of inland Australia.
Sturt's desert pea was formerly called Clianthus formosus and is also known as Willdampia formosa (named after Dampier). The specific name formosa is Latin for "beautiful."
Sturt's desert pea is a slow-growing, creeping plant with stems and leaves appearing soft gray due to a covering of fine hairs. The flowers stand upright on fleshy stalks, up to 30 centimeters tall. The large pea flower can be in various shades of red, with a base of deep red to purple to black.
The genus name Swains...ona honors English botanist Isaac Swainson who maintained a private botanic garden near London in the late 18th century. The former name, Clianthus, is now thought to be confined to New Zealand.
Sturt's desert pea can be found in arid woodlands and on open plains, often as an ephemeral following heavy rain. It is able to withstand temperature extremes in inland deserts, and light frosts are tolerated by established plants.
A protected species in South Australia, Sturt's desert pea flowers and plants must not be collected on private land without the written consent of the owner. Collection on Crown land is illegal without a permit.Continue to 7 of 9 below.

Tasmania: Tasmanian Blue Gum
The Tasmanian blue gum, Eucalyptus glololus Labill, is Tasmania's floral emblem.
The Tasmanian blue gum flowers, larger than those of other Tasmanian eucalypts, usually occur singly in the axils of the leaves. Up to three-quarters of an inch in diameter, the flower buds are described as "coarsely ribbed, warty and are, as in all eucalypts, closed by an operculum or cap representing the sepals and petals."
Large Numbers of Stamens
When the blue gum blooms in early summer, the cap is shed revealing large numbers of white stamens arranged in several rows near the outside. A thick nectar-secreting disk extends partly over the top of the ovary.
From Tasmania to the World
Found throughout the Australian island state of Tasmania, including the historic Royal Hobart Botanical Gardens, the Tasmanian blue gum grows largely in southern and eastern Tasmania and in the middle reaches of the Derwent River. It can grow up to 60 meters (approximately 200 feet).
Introduced overseas, it can be... found in California in the United States, in the Mediterranean region and parts of Africa and India, and in Chile, Argentina, and New Zealand.Continue to 8 of 9 below.

Victoria: Common Heath
The common heath, Epacris impressa, has the distinction of being the first flower to be officially proclaimed an Australian state floral emblem.
It was agreed at a meeting in 1951 by representatives of interested government departments, societies and individuals to name the common heath as the floral emblem of Victoria. The official proclamation of Victoria's state flower was made in 1958.
The generic name Epacris comes from the Greek epi (upon) and akris (hill) and refers to the elevated habitat of some of its species. While the flower is certainly impressive, particularly when blooming en masse, impressa is Latin for "impressed" or "indented" and refers to five dimples on the outside of the basal part of the floral tube.
The flower has a number of color forms including pure white, pale pink, rose pink, crimson, scarlet and rare double-flowered forms. The pink form is the official state flower of Victoria.
The flowers are tubular and sometimes densely... packed around the stem in the leaf axils. This gives the flower cluster a cylindrical brushlike appearance.
A slender, upright shrub growing to a meter (3 feet) or so in height, the common heath flowers from late autumn to late spring, peaking in winter.
Cultivation and Where It Is Found
In Victoria, the common heath is found in coastal regions and nearby foothills, the Grampians, and the Little Desert. It also grows in New South Wales, South Australia, and Tasmania.
The common heath may be propagated from seed and plants are suitable for cultivation in cool, moist areas in well-drained acidic soils.Continue to 9 of 9 below.

Western Australia: Red and Green Kangaroo Paw
The red and green kangaroo paw, Anigozanthos manglesii, is Western Australia's floral emblem. Plants of the genus Anigozanthos have an inflorescence bearing a resemblance to the paw of a kangaroo.
The specific name, manglesii, honors an Englishman. Robert Mangles, who raised the red and green kangaroo paw in his Berkshire garden in the 1830s from seed sent from Australia.
The red and green kangaroo paw is a low shrub growing from an underground stem, with leaves about 30 to 60 centimeters long. The flowering stem grows to about a meter (3 feet) in height.
The stem and the bases of the flowers are usually deep red and covered with wooly hairs. The color then changes abruptly to a brilliant green for most of the length of the flower which splits open to show a smooth pale green interior.
The red and green kangaroo paw flowers in its natural habitat between August and October. It occurs naturally in Western Australia in heath on sandy soil from the Murchison River... in the north to Busselton and Mount Barker in the south and Lake Muir to the east, and on gravel type soil of lateritic origin in the Darling Range.
