Lagerstroemia, commonly known as crepe myrtle, is a genus of around 50 species of deciduous and evergreen trees and shrubs native to the Indian Subcontinent, southeast Asia, northern Australia and parts of Oceania, cultivated in warmer climates around the world. It is a member of the Lythraceae, which is also known as the loosestrife family. The genus is named after the Swedish merchant Magnus von Lagerström, who supplied Carolus Linnaeus with plants he collected. These flowering trees are beautifully coloured and are often planted both privately and commercially. Popular varieties used in modern landscaping include the bright red Dynamite Crepe Myrtle, the deep pink Pink Velour Crepe and the purple Twilight Crepe Myrtle, which also has a bark that changes colours.
Crepe myrtles are chiefly known for their colourful and long-lasting flowers which occur in summer months. Most species of Lagerstroemia have sinewy, fluted stems and branches with a mottled appearance that arises from having bark that sheds throughout the year. The leaves are opposite, simple, with entire margins, and vary from 5–20 cm. While all species are woody in nature, they can range in height from over 30 metres to under one 30 cm, most, however are small to medium multiple-trunked trees and shrubs. The leaves of temperate species provide autumn colour.
Flowers are borne in Summer and Autumn in panicles of crinkled flowers with a crepe-like texture. Colours vary from deep purple to red to white, with almost every shade in between. Although no blue-flowered varieties exist, it is toward the blue end of the spectrum that the flowers trend, with no sight of orange or yellow except in stamens and pistils. The fruit is a capsule, green and succulent at first, then ripening to dark brown or black dryness. It splits along six or seven lines, producing teeth much like those of the calyx, and releases numerous, small, winged seeds.

Polygala is a large genus of flowering plants belonging to the family Polygalaceae. They are commonly known as milkworts or snakeroots. The genus is distributed widely throughout much of the world in temperate zones and the tropics. The genus name Polygala comes from the ancient Greek "much milk", as the plant was thought to increase milk yields in cattle.
Polygala myrtifolia L. is an evergreen 2-4m tall South African shrub or small tree found along the southern and south-eastern coasts, from near Clanwilliam in the Western Cape to KwaZulu-Natal. It is a fast-growing pioneer plant, a typical fynbos component, and may be found on dunes, rocky places, along forest margins, beside streams, and in open grassland.
The thin, oval, mucronate leaves, 25–50 mm long and up to 13 mm wide, are arranged alternately and have entire margins - some forms of P. myrtifolia have thin, needle-like leaves. The attractive mauve sweetpea-like flowers, which close at night, may also be pink, crimson or white, and have a characteristic brush-like tuft protruding from the keel. The fruit is an oval, brown, dehiscent capsule which is narrowly winged. The species is often cultivated in South African gardens and is naturalised in Australia, New Zealand, Norfolk Island and California.

Bougainvillea is a genus of flowering plants native to South America from Brazil west to Perú and south to southern Argentina (Chubut Province). Different authors accept between four and 18 species in the genus.They are thorny, woody vines growing anywhere from 1 to 12 metres tall, scrambling over other plants with their spiky thorns. The thorns are tipped with a black, waxy substance. They are evergreen where rainfall occurs all year, or deciduous if there is a dry season. The leaves are alternate, simple ovate-acuminate, 4–13 cm long and 2–6 cm broad. The actual flower of the plant is small and generally white, but each cluster of three flowers is surrounded by three or six bracts with the bright colours associated with the plant, including pink, magenta, purple, red, orange, white, or yellow. Bougainvillea glabra is sometimes referred to as "paper flower" because the bracts are thin and papery. The fruit is a narrow five-lobed achene.
Many of today's bougainvillea are the result of interbreeding among only three out of the eighteen South American species recognized by botanists. Currently, there are over 300 varieties of bougainvillea around the world. Because many of the hybrids have been crossed over several generations, it is difficult to identify their respective origins. Natural mutations seem to occur spontaneously throughout the world; wherever large numbers of plants are being produced, bud-sports will occur. This had led to multiple names for the same cultivar (or variety) and has added to the confusion over the names of bougainvillea cultivars. This particular type illustrated has a stocky, upright, "tree-like" habit with abundant flowers. Bougainvilleas grow luxuriantly in Melbourne's climate.
