VELVET GROUNDSEL

Roldana petasitis, also known as the velvet groundsel or Californian geranium, is a species of the genus Roldana and family Asteraceae that used to be classified in the genus Senecio. It is native to Central America. Preferring constant heat and thriving in sheltered gardens, it is an evergreen subshrub with weak stems. It grows up to 1.8 m tall and has large leaves with 7 or more broad, blunt lobes.

The flower heads, like daisies, of about 6 ray ligulate petals are borne in foliaceous panicles. The plant blooms from winter to early spring. The plant is native to the subtropical highlands (Sierra Madre del Sur) of Oaxaca in Mexico, south to the tropics in El Salvador, Guatemala and Nicaragua.

Climatically, it is found in the tropical savanna climates grading into the drier semi-arid or temperate wet/dry areas, where it is present from Veracruz in the north to Nicaragua in the south, in both pine-oak and mountain cloud forests between 1,000m and 2,500m, whereas the cristobalensis variety is found in Chiapas, the southern most Mexican state, and in Guatemala between elevations 1,000m and 1,600m. It is naturalised in parts of southeastern Australia and New Zealand.

STRAWFLOWERS

Xerochrysum bracteatum, commonly known as the golden everlasting or strawflower, is a flowering plant in the family Asteraceae native to Australia. Described by Étienne Pierre Ventenat in 1803, it was known as Helichrysum bracteatum for many years before being transferred to a new genus Xerochrysum in 1990.

It grows as a woody or herbaceous perennial or annual shrub up to a metre tall with green or grey leafy foliage. Golden yellow or white flower heads are produced from spring to autumn; their distinctive feature is the papery bracts that resemble petals. The species is widespread, growing in a variety of habitats across the country, from rainforest margins to deserts and subalpine areas. The golden everlasting serves as food for various larvae of lepidopterans (butterflies and moths), and adult butterflies, hoverflies, native bees, small beetles and grasshoppers visit the flower heads.

The golden everlasting has proven very adaptable to cultivation. It was propagated and developed in Germany in the 1850s, and annual cultivars in a host of colour forms from white to bronze to purple flowers became available. Many of these are still sold in mixed seed packs. In Australia, many cultivars are perennial shrubs, which have become popular garden plants. Sturdier, long-stemmed forms are used commercially in the cut flower industry.

AFRICAN BUSH DAISY

Euryops chrysanthemoides (with the common names African bush daisy or bull's-eye) is a small shrub native to Southern Africa that is also grown as a horticultural specimen in tropical to subtropical regions around the world. It occurs in the Eastern Cape, along the coast and inland, to KwaZulu-Natal, Mpumalanga and Swaziland.

It is usually found on forest edges, in riverine bush and in ravines, as well as in coastal scrub, grassland and disturbed areas. It is a compact, densely branched, leafy, evergreen shrub, 0.5 to 2m in height. The species was moved to Euryops from the genus Gamolepis on the basis of chromosome counts. It is a ruderal weed in New South Wales, although it is not weedy in all places where it is cultivated or has naturalised.

TREE DAHLIA

Dahlia imperialis or Bell tree dahlia is an 8-10 metre tall member of the Dahlia genus native to Mexico, Central America and Colombia. It is a plant of the uplands and mountains, occurring at elevations of 1,500–1,700 metres, and its leaves are used as a dietary supplement by the Q'eqchi' people of San Pedro Carchá in Alta Verapaz, Guatemala.

It is a tuberous, herbaceous perennial, rapidly growing from the base after a dormant winter period, developing brittle, cane-like, 4-angled stems with swollen nodes and large tripinnate leaves, those near the ground soon being shed. The pendant or nodding flowerheads are 75-150mm across with ray florets lavender or mauvish-pink in colour. This species is fast-growing, the growth spurt being linked to shorter daylight hours, and usually comes into flower in autumn before the first frost. 

Propagation is by seed or by stem cuttings of some 30 cm long having at least two nodes, laid horizontally below the soil. Some Dahlia species were brought from Mexico to Europe in the 16th century. D. imperialis was first described in 1863 by Benedikt Roezl (1823–1885), the great Czech orchid collector and traveller, who, ten years later in 1872–73, went on his odyssey through the Americas.

YELLOW ECHINACEA

Echinacea is a genus of herbaceous flowering plants in the daisy family, Asteraceae. The nine species it contains are commonly called purple coneflowers. They are endemic to eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming from early to late summer.

The generic name is derived from the Greek word ἐχῖνος (echinos), meaning "sea urchin," due to the spiny central disk. Some species are used in herbal medicines and some are cultivated in gardens for their showy flowers. A few species are of conservation concern.

SWAN RIVER DAISIES

Brachyscome iberidifolia (Swan River Daisy) is a delightful, easy to grow small shrub 15cm to 45cm and is native to Western and central Australia. Masses of purple, blue or white flowers from Spring to Autumn. Ideal for mass planting along borders, rockeries, as ground cover, in tubs or hanging baskets.

Brachyscome is a genus of around 70 species of mostly annual and perennial herbs and a few subshrubs in the daisy family Asteraceae. 65 of these are endemic to Australia, the remainder being found in New Zealand and New Guinea. They have typical "daisy" flower heads with showy ray florets in shades of white, pink, mauve, violet or blue, surrounding a usually narrow group of yellow disk florets.

The leaves are often dissected to varying degrees but may be linear or spathulate. In growth habit they vary between plants with a rosette of basal leaves and more-or-less leafless flower scape, and those with mostly cauline leaves and often prostrate stems.

FELICIA

Felicia amelloides, the blue marguerite or blue daisy, is a species of flowering plant of the family Asteraceae, native to South Africa. F. amelloides is synonymous with, and formerly known as, F. aethiopica, Aster amelloides, Aster capensis, and Aster coelestis.

F. amelloides is an evergreen shrublet usually 30–60 cm tall by 50 cm wide, but sometimes up to 1 m tall, with densely branched and frequently dark red stems, and rough, hairy, ovate green leaves. Striking blue composite flowers with prominent yellow centres, about 30 mm in diameter, and borne on naked stalks up to 180 mm long.

This species is much cultivated, and in the temperate world is usually grown as a half-hardy annual in pots, window-boxes, hanging baskets, and other summer bedding schemes for parks and gardens. Drought- and wind-resistant, it requires a sheltered aspect in full sun, and does not tolerate frost.

CHRYSANTHEMUMS

Although once referred to as Dendranthema, the florists chrysanthemum is now correctly known under its old name. There are about 40 species in the genus Chrysanthemum, mainly from East Asia. In China, where they have been cultivated for over 2,500 years, the chrysanthemum was used medicinally and for flavouring, as well as for ornament. All chrysanthemum flowers are edible, but the flavour varies widely from plant to plant, from sweet to tangy to bitter or peppery. It may take some experimentation to find flavours you like.

The flower is also significant in Japan where it is a symbol of happiness and longevity, and the royal family has ruled for 2,600 years from the Chrysanthemum Throne. The annual species are referred to as Xanthophthalmum and are mainly used for summer bedding or as fillers in borders of perennial flowers. Most chrysanthemums are upright plants with lobed leaves that can be aromatic. The many showy flowerheads, carried at the tips of strong stems, begin to bloom as the days shorten.

Florist's chrysanthemums (Chrysanthemum grandiflorum) are grouped according to form: Irregular incurved, reflexed, regular incurved, intermediate incurved, pompon, single and semi-double, anemone, spoon, quill, spider, brush or thistle, and unclassified, which is a catch-all group for blooms not yet classified or not falling into one of the existing groups. Florists chrysanthemums prefer a heavier richer soil in a sunny position, though they like a spot that offers some afternoon shade. The plants require training and trimming to produce their best flowers. Pinch back when young and disbud to ensure the best flower show. Propagate by division when dormant or from half-hardened summer cuttings.
