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.

FFF226 - CYMBIDIUM ORCHID

Cymbidium, or boat orchids, is a genus of 52 evergreen species in the orchid family Orchidaceae. It was first described by Olof Swartz in 1799. The name is derived from the Greek word kumbos, meaning 'hole, cavity'. It refers to the form of the base of the lip. The genus is abbreviated Cym in horticultural trade.

This genus is distributed in tropical and subtropical Asia (such as northern India, China, Japan, Malaysia, the Philippines, and Borneo) and northern Australia. The larger flowered species from which the large flowered hybrids are derived grow at high altitudes. Cymbidium plants are sympodial and grow to a height of 60 cm and the racemes as high as 90 cm. The raceme grows from the base of the most recent pseudobulb. Each flower can have a diameter of 5 to 10 cm, according to the species.

They bloom during the winter, and each plant can have up to fifteen or more flowers. The fantastic range of colours for this genus include white, green, yellowish-green, cream, yellow, brown, pink, and red [and orange] and black (and there may be markings of other colour shades at the same time), but not blue. The flowers last about ten weeks. They have a waxy texture. The rounded sepals and petals have about the same dimensions. They show very diverse colour patterns, different for every species.

Cymbidium is one of the most popular and desirable orchids in the world because of the beautiful flowers. These plants make great houseplants, and are also popular in floral arrangements and corsages. They have been cultivated for thousands of years, especially in China. Cymbidiums became popular in Europe during the Victorian era. One feature that makes the plant so popular is the fact that it can survive during cold temperatures (as low as 7˚ C or 45˚ F).

HAPPY EASTER TO ALL WHO CELEBRATE IT THIS WEEK!

FFF226 - HIBISCUS 'TROPICANA'

Hibiscus rosa-sinensis, known colloquially as Chinese hibiscus, China rose, Hawaiian hibiscus, and shoe flower, is a species of flowering plant in the Hibisceae tribe of the family Malvaceae, native to East Asia. It is widely grown as an ornamental plant throughout the tropics and subtropics. As it does not tolerate temperatures below 10 °C, in temperate regions it is best grown under glass. However, plants in containers may be placed outside during the summer months or moved into shelter during the winter months.

Numerous varieties, cultivars, and hybrids are available, with flower colours ranging from white through yellow and orange to scarlet and shades of pink, with both single and double sets of petals. The cultivar 'Cooperi' has gained the Royal Horticultural Society's Award of Garden Merit.

Illustrated here is a Flamenco™ Hibiscus 'Tropicana', featuring spectacular long-lasting (4-5 days) large flowers. These varieties have a compact, well branched habit that provides a neat frame for the lush dark green foliage and the many spectacular full blooms that appear continuously during the warmer months.

FFF225 - HYACINTH

Hyacinthus is a small genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. Plants are commonly called hyacinths. Hyacinthus is native to the eastern Mediterranean (from south Turkey to northern Israel), north-east Iran, and Turkmenistan.

Three species are within the genus Hyacinthus:

Hyacinthus litwinowii;

Hyacinthus orientalis - Common, Dutch or Garden Hyacinth;

Hyacinthus transcaspicus.

Some authorities place H. litwonowii and H. transcaspicus in the related genus Hyacinthella, which would make Hyacinthus a monotypic genus.

The Dutch, or Common Hyacinth of house and garden culture (H. orientalis, native to southwest Asia) was so popular in the 18th century that over 2,000 cultivars were cultivated in the Netherlands, its chief commercial producer. This hyacinth has a single dense spike of fragrant flowers in shades of red, blue, white, orange, pink, violet, or yellow. A form of the common hyacinth is the less hardy and smaller blue- or white-petalled Roman hyacinth of florists.

These flowers should have indirect sunlight and are to be moderately watered.Several types of brodiea, squill, and other plants that were formerly classified in the lily family and have flower clusters borne along the stalk also have common names with hyacinth in them. Hyacinths should also not be confused with the genus Muscari, which are commonly known as grape hyacinths.

Hyacinths are sometimes associated with rebirth. The Hyacinth flower is used in the Haftseen table setting for the Persian New Year celebration Norouz held during the Spring Equinox. Hyacinth bulbs are poisonous; they contain oxalic acid. Handling hyacinth bulbs can cause mild irritation to people with sensitive skin. Protective gloves may be worn to avoid irritation.

FFF224 - HYDRANGEA

Hydrangea (common names hydrangea or hortensia) is a genus of 70-75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.

Having been introduced to the Azores, H. macrophylla is now very common, particularly on Faial, which is known as the "blue island" due to the vast number of hydrangeas present on the island. Species in the related genus Schizophragma, also in Hydrangeaceae, are also often known as hydrangeas. Schizophragma hydrangeoides and Hydrangea petiolaris are both commonly known as climbing hydrangeas.

There are two flower arrangements in hydrangeas. Mophead flowers are large round flowerheads resembling pom-poms or, as the name implies, the head of a mop. In contrast, lacecap flowers (shown here) bear round, flat flowerheads with a centre core of subdued, fertile flowers surrounded by outer rings of showy, sterile flowers. The flowers of some rhododendrons can appear similar to those of some hydrangeas, but Rhododendron (including azaleas) is in a different order.

In most species the flowers are white, but in some species (notably H. macrophylla), can be blue, red, pink, light purple, or dark purple. In these species the colour is affected by soil pH. For H. macrophylla and H. serrata cultivars, the flower colour can be determined by the relative acidity of the soil: An acidic soil (pH below 6) will usually produce flower colour closer to blue, whereas an alkaline soil (pH above 6) will produce flowers more pink. This is caused by a colour change of the flower pigments in the presence of aluminium ions which can be taken up into hyperaccumulating plants.
