FFF277 - KURRAJONG

Brachychiton acerifolius, commonly known as the Illawarra Flame Tree, is a large tree of the family Malvaceae native to subtropical regions on the east coast of Australia. It is famous for the bright red bell-shaped flowers that often cover the whole tree when it is leafless. Along with other members of the genus Brachychiton, it is commonly referred to as a Kurrajong.

Brachychiton acerifolius was first described in 1855 by W. Macarthur and C. Moore. It is sometimes spelled as Brachychiton acerifolium, under the assumption that the genus name Brachychiton is (Greek) neuter. In fact, Brachychiton is masculine, and hence the correct species epithet is acerifolius. The name Brachychiton is derived from the Greek brachys, meaning short, and chiton, a type of tunic, as a reference to the coating on the seed.

The specific epithet acerifolius suggests the appearance of the foliage is similar to that of the genus Acer, the maples. This tree is tolerant of temperate climates and is now cultivated world-over for its beauty. However, the maximum height of 40 metres is reached only in the original, warmer, habitat. It usually grows to be about 20 metres. Similarly to its Kurrajong relatives the leaves are variable, with up to 7 deep lobes. It is deciduous - shedding its leaves after the dry season.

The spectacular flowering occurs in late spring and new foliage is ready for the summer rains. In areas where the winter is not particularly dry, this natural rhythm may become somewhat erratic and the tree may flower only partially. Flowers are scarlet bells with 5 partially fused petals. The pod-like fruits (technically known as follicles) are dark brown, wide, boat-shapes and about 10 cm long. They contain masses of thin bristles that stick in the skin, as well as yellow seeds. These are nutritious and were eaten by Aborigines after toasting.

FFF262 - BLUE BUTTERFLY BUSH

Rotheca is a genus of flowering plants in the family Lamiaceae. Estimates of the number of species in the genus vary from about 35 to as many as 60. Three of the species are native to tropical Asia, with the rest occurring in Sub-Saharan Africa. The type species for the genus is Rotheca serrata. It had originally been named Rotheca ternifolia, but this name is now considered illegitimate.

Rotheca myricoides (blue butterfly bush) is native to tropical East Africa and is cultivated as an ornamental throughout the tropics. Rotheca serrata is from tropical Asia and has some medicinal use there. In the 20th century, Rotheca was rarely recognised as separate from Clerodendrum. Rotheca was revived in 1998 as a result of phylogenetic analysis of DNA sequences. It can easily be distinguished from Clerodendrum by a combination of morphological characters.

Rotheca myricoides (also known by its older name Clerodendrum ugadense) is more commonly referred to as the blue butterfly bush. It is called this because of the shape of its flowers. In the early summer, it produces beautiful light blue and lavender flowers that bloom into a shape that resembles a butterfly. It is an evergreen shrub that gets up to 3 metres tall and just as wide. It is native to Kenya and Uganda in East Africa. It enjoys partial shade and requires regular watering.

FFF258 - BOTTLEBRUSH & RAINBOW LORIKEET

This has been a very busy week and I am sorry I have not visited your blogs to see your contributions for last week's Floral Fridays. You all know that I always appreciate your photos and news from your part of the world. At least today I was able to grab the camera and rush out at lunchtime to take some photos in the garden and in the park across the road. We've had a glorious Spring day today and the flowers looked their best.

Callistemon species in the family Myrtaceae have commonly been referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional bottle brush. They are mostly found in the more temperate regions of Australia, especially along the east coast and typically favour moist conditions so when planted in gardens thrive on regular watering. However, two species are found in Tasmania and several others in the south-west of Western Australia. At least some species are drought-resistant and some are used in ornamental landscaping elsewhere in the world. This red bottlebrush is a common garden and street tree in Melbourne.

The rainbow lorikeet (Trichoglossus moluccanus) is a species of parrot found in Australia. It is common along the eastern seaboard, from northern Queensland to South Australia and Tasmania. Its habitat is rainforest, coastal bush and woodland areas. Several taxa traditionally listed as subspecies of the rainbow lorikeet are now treated as separate species Rainbow lorikeets have been introduced to Perth, Western Australia; Auckland, New Zealand; and Hong Kong.

FFF244 - GUNGURRU

Eucalyptus caesia, commonly known as Caesia, Gungurru or Silver Princess, is a mallee of the Eucalyptus genus. It is endemic to the central Wheatbelt region of Western Australia, where it is found on a small number of granite outcrops. The name "silver" refers to the white powder that covers the branches, flower buds and fruit. "Gungurru" comes from the name used by the indigenous Noongar people.

Two subspecies have been identified: caesia (about 6–9 metres tall) and magna (up to 15 metres tall). The bark is red-brown, of the curly minni ritchi type. Branches tend to flail or weep on the ground. Trees have large red-pink or white flowers, 40-50mm in diameter. They are widely grown as ornamental native plants, but have become rare in the wild.

Eucalyptus caesia was named in 1867 by George Bentham from specimens collected by James Drummond in 1847. Drummond made his collection too late in the season to gather buds and flowers, and this made later identification difficult. During the Elder Scientific Exploring Expedition of 1891–2, Richard Helms gathered specimens of a Eucalyptus that the Indigenous Australians of the area called "Gungurru".

This was almost certainly Eucalyptus woodwardii, but in 1896 it was misidentified by Mueller and Tate as E. caesia. This led to the incorrect application of the common name "Gungurru" to E. caesia, and to confusion about the species' distribution. Authenticated collections of E. caesia were later made by A. Morrison in 1885, and in 1923 Charles Gardner collected specimens from a form with considerably larger leaves, buds, flowers and fruits. This was later recognised as subspecies magna by Brooker and Hopper (1982), with the original form being designated subspecies caesia.

FFF233 - PROTEA 'PINK ICE'

Cold hardiness and beautiful pink and black flowers are the hallmarks of the hybrid Protea, 'Pink Ice.' A cross between the South African natives, mink protea (Protea neriifolia) and stink-leaf sugarbush (P. susannae), this evergreen is an upright to loosely rounded shrub that blooms in Autumn and Winter. Its stellar blooms are beautiful when cut and last for two to three weeks in a vase.

The narrow, oval foliage of this shrub is medium green with a leathery, hard texture. When Autumn and Winter days shorten and temperatures grow cooler, the leaf edges blush rosy pink. Each blossom resembles a torch with hundreds of magenta-rose bracts. The tips of the bracts are edged with feathery burgundy black hairs. This Protea is among the easiest to grow. It tolerates slightly acid and alkaline soils as well as climates that are wet in winter and dry in summer, or dry in winter and wet in summer.

For best performance, plant it in full sun and alkaline soil that is moderately infertile. Soil must be fast-draining and porous; moist soils encourage fungal diseases. Amend loam and clay soils with grit and coarse organic matter to improve aeration and drainage. Do not fertilise, especially with phosphorus which causes proteas to falter. Plant this showy shrub in a prominent location to show off its magnificent flowers.

All proteas are short-lived surviving 10 to 15 years at most. Take stem cuttings from older plants to replace older, failing specimens. Trim spent flowers off in spring to encourage fuller growth and more blooms by early winter.

FFF228 - GUMTREE

Eucalyptus leucoxylon, commonly known as the Yellow Gum, (South Australian) Blue Gum or White Ironbark, is a small to medium-sized tree with rough bark on the lower 1-2 metres of the trunk, above this, the bark becomes smooth with a white, yellow or bluish-grey surface. Adult leaves are stalked, lanceolate to broad-lanceolate, to 13 x 2.5 cm, concolorous, dull, green. Flowers in white, pink or red appear during winter.

E. leucoxylon is widely distributed on plains and nearby mountain ranges or coastal South Australia, where it is known as the Blue Gum and extends into the western half of Victoria where it is known as the Yellow gum.The species has been divided into numerous varieties and subspecies. A spectacular red-flowered form of uncertain provenance Eucalyptus leucoxylon ‘Rosea’ (shown here) is widely planted as an ornamental plant, it flowers profusely in winter. A threatened subspecies known as the Bellarine Yellow Gum (Eucalyptus leucoxylon subsp. bellarinensis) is endemic to the Bellarine Peninsula at the south-eastern end of the species' range. The leaves are distilled for the production of cineole based eucalyptus oil.

FFF213 - FRANGIPANI

Plumeria is a genus of flowering plants in the dogbane family, Apocynaceae. It contains primarily deciduous shrubs and small trees. They are native to Central America, Mexico, the Caribbean, and South America as far south as Brazil but can be grown in tropical and sub-tropical regions.

Plumeria is related to the Oleander, Nerium oleander, and both possess an irritant, rather similar to that of Euphorbia. Contact with the sap may irritate eyes and skin. Each of the separate species of Plumeria bears differently shaped, alternate leaves with distinct form and growth habits. The leaves of P. alba are quite narrow and corrugated, whereas leaves of P. pudica have an elongated shape and glossy, dark-green colour. P. pudica is one of the everblooming types with non-deciduous, evergreen leaves. Another species that retains leaves and flowers in winter is P. obtusa; though its common name is "Singapore," it is originally from Colombia.

Plumeria flowers are most fragrant at night in order to lure sphinx moths to pollinate them. The flowers have no nectar, however, and simply dupe their pollinators. The moths inadvertently pollinate them by transferring pollen from flower to flower in their fruitless search for nectar.

Plumeria species may be propagated easily from cuttings of leafless stem tips in spring. Cuttings are allowed to dry at the base before planting in well-drained soil. Cuttings are particularly susceptible to rot in moist soil. In order to get the most from a plumeria plant with respect to growth, size, blooms, and scent, there is a fine balance that must be maintained. Ideally, a plumeria is in its element when it can have plenty of sun and appropriate water, so as to maintain soil moistness just above a state of dryness. On the other hand, if the plant receives a lesser amount of sun, then a lesser amount of watering is necessary - again, to ensure that soil moistness stays just above the dry state. The more sun, the more water. The less sun, the less water. A common mistake of novice plumeria growers is to overwater the plant when it is not able to be exposed to enough sun, thereby resulting in a rotted root system. Conversely, if a plumeria plant is able to receive maximum exposure to the sun, but they aren't watered enough, the plant will die.

FFF186 - WILLOW-LEAF WATTLE

Acacia iteaphylla (F.Muell. ex Benth.) occurs naturally in South Australia extending from the Flinders Ranges across to the Gawler Ranges and the Eyre Peninsula. Commonly called Willow-leaf Wattle, this shapely decorative shrub is hardy and fast growing and flowers intermittently throughout the year with a peak flowering period in spring. It is versatile in its habit growing to a height of 2-4 m with some forms becoming upright, whilst others are pendulous and bushy.

The slender phyllodes of A. iteaphylla are from 50 -100 mm long and are broadly linear with a small gland at the base. They are blue-green in colour and arranged alternately, almost at right angles to the stems. The perfumed flower heads are produced in clusters of pale yellow balls which contrast pleasingly with the foliage. The buds are attractively enclosed by conspicuous pale, brown-tipped bracts. The flowers are followed by masses of flattened blue-green seed pods which become brown when mature.

A low growing form of A. iteaphylla has been recognised. It differs from other known forms in having low arching, slightly pendulous branches and grows to 0.5 m high by 4 m across. This plant, which originated as a variant in a batch of seedlings, has been registered as the cultivar Acacia 'Parsons Cascade'. To retain its low spreading growth habit the cultivar should be propagated only from cuttings as it will not necessarily breed true from seed.

Acacia iteaphylla grows best in a well drained sunny position. It is moderately frost tolerant and moderately salt tolerant. It can be propagated from cuttings taken between February and April. Seed germinates readily but should be scarified or treated with boiling water before sowing. Light pruning throughout the development of the plant will keep it vigorous and encourage bushiness. An application of a complete fertiliser in spring and a slow release fertiliser in autumn is also recommended.

Pests noted on A. iteaphylla are the acacia bug, which rasps the leaf tissue causing brown lesions to appear on leaves and stems, and scale insects. Chemical control of acacia bug is difficult as the insect is usually no longer present when the damage is noticed. Affected parts of the plant should be pruned out. Scale insects may be controlled by chemical means but low toxicity products should be selected. Consult a local horticultural specialist for advice.

FFF173 - CASSIA FISTULA

Cassia fistula, known as the golden shower tree and by other names, is a flowering plant in the family Fabaceae. The species is native to the Indian subcontinent and adjacent regions of Southeast Asia. It ranges from southern Pakistan eastward throughout India to Myanmar and Thailand and south to Sri Lanka. In literature, it is closely associated with the Mullai (forest) region of Sangam landscape. It is the national tree of Thailand, and its flower is Thailand's national flower. It is also the state flower of Kerala in India and of immense importance amongst the Malayali population. It is a popular ornamental plant and is also used in herbal medicine.

The golden shower tree is a medium-sized tree, growing to 10–20 m tall with fast growth. The leaves are deciduous, 15–60 cm long, and pinnate with three to eight pairs of leaflets, each leaflet 7–21 cm long and 4–9 cm broad. The fragrant flowers are produced in pendulous racemes 20–40 cm long, each flower 4–7 cm diameter with five yellow petals of equal size and shape. The fruit is a legume, 30–60 cm long and 1.5–2.5 centimetres broad, with a pungent odour and containing several seeds. The tree has strong and very durable wood.

Cassia fistula is widely grown as an ornamental plant in tropical and subtropical areas. It blooms in late spring. Flowering is profuse, with trees being covered with yellow flowers, many times with almost no leaf being seen. It will grow well in dry climates. Growth for this tree is best in full sun on well-drained soil; it is relatively drought tolerant and slightly salt tolerant. It will tolerate light brief frost, but can get damaged if the cold persists. It can be subject to mildew or leaf spot, especially during the second half of the growing season. The tree will bloom better where there is pronounced difference between summer and winter temperatures.

In Ayurvedic medicine, the golden shower tree is known as aragvadha, meaning "disease killer". The fruit pulp is considered a purgative, and self-medication or any use without medical supervision is strongly advised against in Ayurvedic texts. Though its use in herbalism has been attested to for millennia, little research has been conducted in modern times.

FFF44 - CRAB APPLE FLOWERS

Crab apple is a term used for several species of Malus in the family Rosaceae, which are characterised by small sour fruit resembling familiar table apples (Malus domestica). They are usually small trees or shrubs. The plants are grown primarily as ornamentals, although a few growers produce the fruit commercially. The fruit is preserved or pickled or it is used in making jellies. Most crab apples are grown for their ornamental value, and cultivars are chosen because of their beautiful flowers, foliage, or fruit.

The flower is similar to that of the apple. Bees freely visit the flowers, for both nectar and pollen. Like the apple, the crab apple appears to require cross-pollination between cultivars by insects. Self-pollination is impossible and pollinating insects are absolutely needed. Considering that the only difference between the crab apple and the apple is fruit size, it seems reasonable that the most effective pollinator of apples, the honey bee, should be equally effective on the crab apple.
Crab apple species freely hybridise among themselves and with domestic apples. They produce copious and highly fertile pollen, thus are used as pollenisers in apple orchards. Varieties of crabapple are selected to bloom contemporaneously with the apple variety in an orchard planting, and the crabs are planted every sixth or seventh tree, or limbs of crab are grafted onto some of the apple trees. In emergencies a bucket or drum bouquet of crab apple blossoms are placed near the beehives as orchard pollenisers.

FFF42 - CORAL TREE

Erythrina is a genus of flowering plants in the pea family, Fabaceae. It contains about 130 species, which are distributed in tropical and subtropical regions worldwide. They are trees, growing up to 30 m in height. The generic name is derived from the Greek word ερυθρóς (erythros), meaning "red," referring to the flower color of certain species.

Particularly in horticulture, the name coral tree is used as a collective term for these plants. "Flame trees" is another vernacular name, but may refer to a number of unrelated plants as well. Many species of Erythrina have bright red flowers, and this may be the origin of the common name. However, the growth of the branches can resemble the shape of sea coral rather than the color of Corallium rubrum specifically, and this is an alternative source for the name. Other popular names, usually local and particular to distinct species, liken the flowers' red hues to those of a male chicken's wattles, and/or the flower shape to its leg spurs. Commonly seen Spanish names for any local species are bucaré, frejolillo or porotillo, and in Afrikaans some are called kaffirboom. Mullumurikku is a widespread name in Kerala.

AUSTRALIAN GOLD

Acacia is the largest genus in the family Mimosaceae, the Mimosa family, which is mainly tropical and sub-tropical in distribution.The generic name Acacia is derived from the Greek 'akis', a point, referring to the spiny thorns of some species. There are more than 900 species of Acacia in Australia, making it the largest genus in the Australian flora.

Acacia pycnantha, Golden Wattle, is a shrub or small tree about 4 to 8 metres tall. The specific name pycnantha from the Greek 'pyknos', meaning 'dense', and 'anthos', meaning 'a flower', refers to the dense clusters of flowers.  In spring large fluffy golden-yellow flower-heads with up to eighty minute sweetly scented flowers provide a vivid contrast with the foliage.

Golden Wattle occurs in the understorey of open forest or woodland and in open scrub formations in South Australia, Victoria, New South Wales and the Australian Capital Territory, in temperate regions with mean annual rainfall of 350 mm to 1000 mm. It regenerates freely after fires, which usually kill the parent plants but stimulate the germination of seeds stored in the soil if rain follows soon after.

The brilliant yellow, fragrant flowers of Golden Wattle make it a popular garden plant. It is moderately frost tolerant and grows well in a wide range of soils provided drainage is effective, but tends to be short-lived in cultivation. It is easily propagated from seed soaked in hot water to break the hard seed coat, and the seedlings can be transplanted to pots of soil mix for growing on before planting out in a lightly shaded or open position.

Golden Wattle flowers have been used in perfume making. It was introduced to horticulture in the northern hemisphere about the middle of the nineteenth century. In Britain it survives outdoors only in the mildest areas. In California it has escaped from garden cultivation and now grows wild but it is not considered a pest. In South Africa, however, it has become a significant weed species.

The adoption of the Golden Wattle as the national flower tends to be confirmed by its introduction into the design of the Australian armorial bearings on the recommendation of the Rt Hon. Andrew Fisher, Prime Minister of Australia, when the Commonwealth Armorial Ensigns and Supporters were granted by Royal Warrant on 19 September 1912.  Acacia pycnantha enjoyed popular acceptance as Australia's national flower for much of this century but it was not proclaimed as the national floral emblem until 1988, the year of Australia's bicentenary.

The Gazettal is dated 1 September 1988, signed by the Governor General, Sir Ninian Stephen, on 19 August 1988.A ceremony was held on 1 September 1988 at the Australian National Botanic Gardens when the Minister for Home Affairs, Robert Ray, made the formal announcement, and the Prime Minister's wife, Mrs Hazel Hawke, planted a Golden Wattle. Four years later, in 1992, the 1 September was formally declared 'National Wattle Day' by the Minister for the Environment, Mrs Ros Kelly at another ceremony at the Australian National Botanic Gardens. The Gazettal is dated 24 August 1992 and was signed by the Governor General, Bill Haydon, on 23 June 1992.
