WHITE HAEMANTHUS

Haemanthus albiflos is a species of flowering plant in the family Amaryllidaceae, native to the coast and mountains of South Africa. It is sometimes given the English name paintbrush, not to be confused with Castilleja species which also have this name. It is an evergreen bulbous perennial geophyte, prized horticulturally for its unusual appearance and extreme tolerance of neglect. H. albiflos is the only Haemanthus species found in both winter and summer rainfall regions, and has a mainly coastal distribution from the southern Cape through the Eastern Cape to KwaZulu-Natal, showing a preference for cool, shady spots.

MAGNOLIA

Magnolia laevifolia grows as a small tree bearing multitudes of golden buds. Unlike other magnolia relatives, the buds form in the leaf axils and along the stem. The bright, hairy bud scales (perules) split off at blooming time to reveal an ivory flower with "butter-yellow stamens like lashes opening to the sun," described one grower. The waxy, chalice-like flower has a delicate perfume, and can bloom from mid-winter and continue late into the autumn. A tree in full bloom can perfume the air for several metres around it.

The leaves are oval-shaped and tough with a golden edge.There are 41 species of what was once called Michelia in China (all of which have been lumped into the genus Magnolia), and 23 of these grow in Yunnan. Some are two hundred years old and grow at altitudes as high as 9000 feet, far higher than other varieties of magnolias can survive.

BUTTERFLY

The small white cabbage butterfly (Pieris rapae) is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is also known as the small cabbage white and in New Zealand, simply as white butterfly. The names "cabbage butterfly" and "cabbage white" can also refer to the large white.

The butterfly can be distinguished by the white colour with small black dots on its wings. It is distinguished from the large white, by its smaller size and lack of the black band at the tip of their forewings. It is widespread and populations are found across Europe, North Africa, Asia, and Great Britain. It has also been accidentally introduced to North America, Australia and New Zealand.

The caterpillar of this species is seen as a pest for commercial agriculture. Often referred to as the "imported cabbageworm" they are a serious pest to cabbage and other mustard family crops.

CALADENIA

Caladenia catenata, commonly known as white caladenia, white fingers and lady's fingers, is a plant in the orchid family Orchidaceae and is endemic to New South Wales, Queensland and Victoria. It is a ground orchid with a single hairy leaf and one or two white, sometimes pink flowers on a thin, sparsely-hairy stem. It is similar to Caladenia carnea but lacks the red and white bars on the labellum of that species. 

There are one or two flowers borne on a slender, sparsely hairy spike 10–30 cm high. The sepals and petals are glistening white, rarely pink and are sparsely hairy on the lower part of their backs. The dorsal sepal is linear to oblong, erect or slightly curved forward and is 15–22 mm long. The lateral sepals and petals are about the same length as the dorsal sepal and spreading. The labellum is white or pinkish with a yellowy-orange tip. It is 8–10 mm long, 6–18 mm wide when flattened and has three lobes. The central lobe is triangle-shaped, longer than the lateral lobes, curves downward and has finger-like teeth on its edges. The lateral lobes are narrow and may have a few teeth near their tips. There are two rows of yellow or white, club-shaped calli on the centre of the mid-lobe but only as far forward as the front of the lateral lobes.

Flowering occurs from August to November, earlier in New South Wales than Victoria. This Caladenia is uncommon in Victoria where it grows in scattered populations in forest and woodland east of Melbourne. It is more common in New South Wales where it usually grows in sandy soil in coastal forest and shrubland. It is probably the most common Caladenia in the Sydney region.

IBERIS

Iberis sempervirens (evergreen candytuft, perennial candytuft) is a species of flowering plant in the family Brassicaceae, native to southern Europe. It is a spreading subshrub growing to 30 cm high by 40 cm broad. As an ornamental plant it is a spring-blooming favourite, often seen cascading over rocks and walls, or used as groundcover. The glossy, evergreen foliage forms a billowing mound, with many fragrant, pure white flowers for several weeks during spring and early summer.

When grown in a garden it may require light pruning right after blooming, but otherwise plants can be left alone in fall and early spring. It is drought-tolerant once established. It prefers a well-drained site, so heavy clay soils that stay wet in winter should be avoided. It is not easily divided. Iberis is so named because many members of the genus come from the Iberian Peninsula. Sempervirens means "always green", referring to the evergreen foliage. This plant and the cultivar 'Snowflake' have gained the Royal Horticultural Society's Award of Garden Merit.

BOTTLEBRUSH

Callistemon is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia but widely cultivated in many other regions and naturalised in scattered locations. Their status as a separate taxon is in doubt, some authorities accepting that the difference between callistemons and melaleucas is not sufficient for them to be grouped in a separate genus.

Callistemon species 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.

Melaleuca pallida, commonly known as lemon bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to eastern Australia. (Some Australian state herbaria use the name Callistemon pallidum). It is an upright shrub with thin, spreading branches, silvery new growth and pale yellow, sometimes pinkish bottlebrush flowers. Callistemon pallidum is a hardy plant, adaptable to many soils but needs full sun.

STEPHANOTIS

Stephanotis floribunda syn. S. jasminoides (Madagascar jasmine, waxflower, Hawaiian wedding flower, bridal wreath) is a species of flowering plant in the family Apocynaceae, native to Madagascar. Growing to 6 m or more, it is an evergreen woody climber with glossy, leathery oval leaves and clusters of pure white, waxy, intensely fragrant tubular flowers. Grown commercially, the trumpet-shaped blooms are in season year-round, provided they are given enough light and water, and are a popular component of bridal bouquets.

It is a vigorous climber, tough-stemmed, bearing dark green leathery leaves, which grow in pairs at regular intervals along the vine. It grows best in sunny, tropical conditions, or inside. They can grow from 2–6 meters, and are widely cultivated as garden plants. They can flourish for years, grown indoors on a sunny windowsill. They can be moved outside or into a greenhouse during the summer. Few resources are published relating to the culture of this woody vine.

In areas where the outside winter temperature drops below 4 °C, Stephanotis floribunda can be wintered over in greenhouse or household settings. During the summer growth season, this vine requires full sun, abundant water, high humidity and a balanced fertiliser. The vine will need to be trellised due to the vigorous growth habit. As temperatures begin to cool, pots should be brought indoors and placed in the sunniest location available. If the temperature in the home is on the cool side, the vines slow in their growth and thus should be watered very infrequently. Kept on the cool, sunny and dry side, the plants will "rest" until the outside temperatures begin to rise again, at which time they may be eased back into full sun. They may continue to grow during this period, but growth is often slower and less vigorous. When the weather warms, moving the vines into a full sun exposure too quickly will result in leaf blister and sun burns on the plant, rendering it less attractive and damaging the plant's ability to produce food.

In ideal conditions, these vines may be kept in bloom all year, but this is difficult in the home setting, especially where Australian possums, to which the leaves are highly attractive, are present. This plant has gained the Royal Horticultural Society's Award of Garden Merit. Stephanotis floribunda appears to do best if root bound, thus it is best to not plant the vines in an over-sized container. The soil mixture used should have a high content of loam and peat moss with generous drainage material such as perlite or coarse sand. A citrus-type soil mixture works well in most home situations. A soil mixture that retains too much water will lead to root rot.

ABUTILON

Abutilon or 'Chinese lanterns' are closely related to hibiscus, and most of the hundred or so species have pendulous, hibiscus-like flowers. Cultivars produced by hybridising some of the South American abutilons have all been placed in one group known as Abutilon x hybridum, and these are the ones most commonly grown in Australian gardens.

They have a wispy, delicate form and colourful, lantern-shaped flowers. For gardeners who prefer plants with a more dense habit, new compact varieties are also available. Another popular abutilon is Abutilon megapotamicum, which is a prostrate or ground covering species with small orange flowers. Abutilon are evergreen shrubs with attractive maple-like leaves and an open, pendulous habit. They grow to about 2-3 metres tall.

Flowers in the Southern Hemisphere are produced in September to December, but they spot flower at other times. Flower colours include white, pink, red, yellow, orange and salmon. These plants grow well in most parts of Australia, except for the very cold mountain zones. In inland areas be sure to water well and keep protected with mulch. In hot inland climates abutilons appreciate some light shade.

LANTANA

Lantana is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae. They are native to tropical regions of the Americas and Africa but exist as an introduced species in numerous areas, especially in the Australian-Pacific region. The genus includes both herbaceous plants and shrubs growing to 0.5–2 m tall. Their common names are shrub verbenas or lantanas. Some species are invasive, and are considered to be noxious weeds, such as in South Asia, Southern Africa and Australia. In the United States, lantanas are naturalised in the southeast, especially coastal regions of the Carolinas, Georgia, Florida, and the Gulf Coast.

The generic name originated in Late Latin, where it refers to the unrelated Viburnum lantana. Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colours exist as new varieties are being selected. The flowers typically change colour as they mature, resulting in inflorescences that are two- or three-coloured. "Wild lantanas" are plants of the unrelated genus Abronia, usually called "sand-verbenas".

Lantana camara blanca, shown here is a small perennial shrub which can grow to around 2m in height and forms dense thickets in a variety of environments. It has small tubular shaped flowers, each of which has four petals and are arranged in clusters at the end of stems. Flowers are yellow and white and after pollination occurs the colour of the flowers change (typically from yellow to white); this is believed to be a signal to pollinators that the pre-change colour contains a reward as well as being sexually viable, thus increasing pollination efficiency.

DAISIES

Leucanthemum × superbum (or Shasta daisy) is a commonly grown flowering herbaceous perennial plant in the family Asteraceae with the classic daisy appearance of white petals (ray florets) around a yellow disc, similar to the oxeye daisy Leucanthemum vulgare Lam. but larger. Shasta daisies are characterised by a distinct odour which some find unpleasant.

It originated as a hybrid produced in 1890 by the American horticulturist Luther Burbank from a number of daisies. First, he crossed Leucanthemum vulgare with Leucanthemum maximum (Ramond) DC.; this double hybrid was itself crossed with Leucanthemum lacustre (Brot.) Samp. The resulting Leucanthemum triple hybrid was crossed with Nipponanthemum nipponicum (Franch. ex Maxim.) Kitam., creating an intergeneric cross of species from three continents. It was named after Mount Shasta, because its petals were the colour of the snow.

Some members of the genus are considered noxious weeds, but the Shasta daisy remains a favourite garden plant and ground-cover. Many cultivars are suitable for cut flowers, such as 'Becky', 'Esther Read', 'Silberprinzesschen' (Silver Princess), 'Snow Lady', 'Tinkerbell', 'Wirral Pride', 'Wirral Supreme'. The cultivar 'T.E. Killin' has gained the Royal Horticultural Society's Award of Garden Merit. The illustrated variety is 'Snowdrift', which we have growing in our garden.

ECHINOPSIS

A photo of a lovely Echinopsis spp cactus flowering in the Royal Botanic Gardens in Melbourne. The only cactus genus that is more confusing than Echinopsis is that of Opuntia. In both cases, there is a great number of species (over 100) and a tremendous amount of variation. In Echinopsis plants range from very small, flattened-globose plants to quite large, treelike giants. As a result, there is a long list of synonymous names for many of the species. Some synonyms referring to other synonyms that refer to a subspecies of some seemingly distinct species. Sorting through these names often feels like a wild goose chase and is quite frustrating.

In more recent thinking, the previous two genera of Trichocereus and Lobivia are included with Echinopsis. However, it is not at all uncommon for enthusiasts to use all three names in discussion even if their labels read Echinopsis! This usage reflects the general (inexact) situation that the larger, columnar members are distinguished as Trichocereus while Lobivia includes a select group of smaller, not-as-spiny plants which typically flower from low on the plant similar to most Rebutia species. This leaves the bulk of plants referred to as Echinopsis to be mostly spiny, ribbed, globose plants.

The main factor that ties these plants together are their very large, showy flowers. These flowers are all very similar in structure – funnel shaped, with hairy/wooly scaled floral tubes which give rise to hairy, globular fruit filled with a soft, mushy pulp. The flowers seldom last more than a single day and may be diurnal or nocturnal depending on the species. These species hybridise easily and have resulted in a tremendous number of hybrids that some cactus growers specialise in or grow exclusively. There are certainly enough hybrids to keep even ardent hobbyists busy.

Because of their exceptional flowers, many Echinopsis species are found in garden centres and collections world-wide. The larger species (aka Trichocereus) are also popular landscape plants in warmer parts of the world. While there are a number of species common in cultivation, there are as many or more unknown hybrids in the trade. These hybrids are easy-to-grow and produce nice flowers, but buyer beware if exact names are desired. Plants of this genus are widespread throughout South America and inhabit a wide range of habitats and climates.

EPIPHYLLUM

Epiphyllum crenatum is a species of cactus and one of the most important parents in creating the Epiphyllum-hybrids commonly cultivated throughout the world. It is cultivated for its beautiful diurnal flowers. It is found naturally from Mexico (Oaxaca & Chiapas) to Honduras. It is epiphytic (grows upon another plant) or lithophytic (grows on rocks) in moist or wet forests, sometimes in oak forests (1.750 m alt. or less).

It is an easily cultivated, fast growing epiphyte. Needs compost containing plenty of humus and sufficient moisture in summer. Should not be kept under 12°C in winter. Can be grown in semi-shade or full sun. Extra light in the early spring will stimulate budding. Flowers in late spring or early summer.

MELBOURNE STREET TREES 190 - BLACK LOCUST

Robinia pseudoacacia, commonly known as the black locust, is a tree of the genus Robinia in the subfamily Faboideae of the pea family Fabaceae. It is native to the southeastern United States, but has been widely planted and naturalised elsewhere in temperate North America, Europe, Southern Africa, Australia and Asia and is considered an invasive species in some areas.

A less frequently used common name is false Acacia, which is a literal translation of the specific epithet. It was introduced into Britain in 1636. With a trunk up to 0.8 m diameter (exceptionally up to 52 m tall and 1.6 m diameter in very old trees), with thick, deeply furrowed blackish bark. The leaves are 10–25 cm long, pinnate with 9–19 oval leaflets, 2–5 cm long and 1.5–3 cm broad. Each leaf usually has a pair of short spines at the base, 1–2 mm long or absent on adult crown shoots, up to 2 cm long on vigorous young plants.

The intensely fragrant (reminiscent of orange blossoms) flowers are white to lavender or purple, borne in pendulous racemes 8–20 cm long, and are edible. In France and in Italy Robinia pseudoacacia flowers are eaten as beignets after being coated in batter and fried in oil.

The fruit is a legume 5–10 cm long, containing 4–10 seeds. Although the bark and leaves are toxic, various reports suggest that the seeds and the young pods of the black locust are edible. Shelled seeds are safe to harvest from summer through fall, and are edible both raw and/or boiled. Due to the small nature of Black Locust seeds, shelling them efficiently can prove tedious and difficult.

The name locust is said to have been given to Robinia by Jesuit missionaries, who fancied that this was the tree that supported St. John in the wilderness, but it is native only to North America. The locust tree of Spain (Ceratonia siliqua or Carob Tree), which is also native to Syria and the entire Mediterranean basin, is supposed to be the true locust of the New Testament.

This tree is a garden escapee and finds itself close to the waters of the Darebin Creek in the Parklands in the Melbourne suburbs.

GARDENIA IN OUR GARDEN

Gardenia augusta 'Super Star' in the family Rubiaceae is a wonderful compact gardenia that looks good and smells even better! Super Star is a compact and low growing gardenia with narrow glossy, deep green foliage and masses of single, white, highly perfumed flowers throughout the year. Perfect for a position in sun or shade, and once established is tolerant of a wide range of conditions including heat, frost and drought. A landscapers dream. Gardenia Super Star can be grown Australia wide. It is drought hardy once established and tolerant of both heat and frost.

A plant for full sun to part shade, Gardenias prefer a rich, well drained soils with a neutral to slightly acidic pH. Heavy soils should be improved with organic matter prior to planting. Raised beds are recommended for very heavy clay soils. All Gardenias require good drainage. They are intolerant of very heavy or waterlogged soils. Space 60cm apart for a hedge or border. Planting holes should be approximately twice the size of the pot to be planted and back filled with soil that has been enriched with organic matter. Make sure that the rootball sits no lower than the surrounding soil. Water deeply after transplanting.

Mulching is beneficial to reduce moisture loss from the soil and to protect surface roots from extremes of temperature. Mulch should be around 10cm deep but kept 5cm-10cm away from the stem. Requires no pruning to maintain a neat shape, however if a more formal shape is desired, light pruning after flowering is all that is required. Gardenias should be fed during spring and summer using a good quality complete fertiliser.

MELBOURNE STREET TREES 174 - SNOW IN SUMMER

Melaleuca linariifolia, commonly known as snow-in-summer, narrow-leaved paperbark, flax-leaved paperbark and in the language of the Gadigal people as budjur. It is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales and Queensland in Australia. A hardy plant, it flowers prolifically in late spring or summer, making it a popular garden shrub or small tree in temperate places. Melaleuca trichostachya is a similar species but its leaves are arranged differently and the fruits have projecting valves.

Melaleuca linariifolia is a small tree growing to a height of 6–10 m with distinctive and attractive white or creamy white, papery bark and a dense canopy. Its leaves are arranged in alternating pairs (decussate), glabrous except when very young, 17–45 mm long, 1–4 mm wide, linear to lance-shaped and with a distinct mid-vein. The flowers are white to creamy-white, perfumed and arranged in spikes on the ends of branches which continue to grow after flowering, sometimes also in the upper leaf axils.

Each spike is up to 40 mm wide and long and contains 4 to 20 individual flowers. The petals are 2.5–3.3 mm long and fall off as the flower matures. The stamens are arranged in five bundles around the flower and each bundle contains 32 to 73 stamens. The flowers cover the tree over a relatively short period, between October and February and are followed by fruit which are woody capsules, 2.5–4 mm wide and 4–5 mm long scattered along the stems.The fruiting capsules have valves which do not project beyond the rim of the capsule.

Melaleuca linariifolia is cultivated as an ornamental tree for streets, parks and gardens and is also used as a screen or windbreak in Australia and overseas. It is popular as a nature strip tree in Melbourne in Victoria. It tolerates both dry and boggy conditions and is frost hardy. It should be planted with caution as it can damage wastewater pipes, and is easily ignitable, so should not be planted in fire-prone areas. It has also become a garden escape in Western Australia, however it suitable for planting under powerlines and is a food or habitat sources for native animals, including many insects. There is a range of cultivars that has been developed including dwarf forms such as "Snowstorm" (to 1.5 metres tall) and "Seafoam" (2.5 metres tall).
