|Tibouchina urvilleana flower, Sri Lanka|
Tibouchina urvilleana is a species of flowering plant in the family Melastomataceae, native to Brazil. Growing to 3–6 m (10–20 ft) tall by 2–3 m (7–10 ft) wide, it is a sprawling evergreen shrub with longitudinally veined, dark green hairy leaves. Clusters of brilliant purple flowers up to 10 cm (4 in) in diameter, with black stamens, are borne throughout summer and autumn.
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined.
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma ("seed").
Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".
Common names include:
The specific epithet urvilleana commemorates the 19th century French explorer and botanist Jules Dumont d'Urville.
Jules Sébastien César Dumont d'Urville was a French explorer and naval officer who explored the south and western Pacific, Australia, New Zealand and Antarctica. As a botanist and cartographer he gave his name to several seaweeds, plants and shrubs, and places such as d'Urville Island in New Zealand.
T. urvilleana has gained the Royal Horticultural Society's Award of Garden Merit.
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity.
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions.
With a minimum temperature of 3 °C (37 °F), it requires some winter protection, and in temperate areas is often grown in a conservatory. However, it can also be grown outside in a sunny, sheltered spot. Plants are best grown in acidic and well-drained soils and spread by suckers. It can be trained as a vine and grown on a trellis.
Molinia caerulea, the purple moor-grass, is a species of grass that is native to Europe, west Asia, and north Africa. It grows in locations from the lowlands up to 2,300 m (7,546 ft) in the Alps. Like most grasses, it grows best in acid soils, ideally pH values of between 3.5 and 5, however, it can continue to live under more extreme conditions, sometimes to as low as 2. It is common on moist heathland, bogs and moorland throughout Britain. Introduced populations exist in northeastern and northwestern North America.
Heliotropium arborescens, the garden heliotrope, is a species of flowering plant in the borage family Boraginaceae, native to Peru. Growing to 1.2 m (3.9 ft) tall and broad, it is a bushy, evergreen, short-lived shrub with dense clusters of bright purple flowers, notable for their intense, rather vanilla-like fragrance. Common names also include cherry pie and common heliotrope. Note that the common name "garden heliotrope" may also refer to valerian (herb), which is not closely related.

Berberis thunbergii, the Japanese barberry, Thunberg's barberry, or red barberry, is a species of flowering plant in the barberry family, Berberidaceae, native to Japan and eastern Asia, though widely naturalized in China and in North America. Growing to 1 metre (3.3 ft) tall by 2.5 metres (8.2 ft) broad, it is a small deciduous shrub with green leaves turning red in the autumn, brilliant red fruits in autumn and pale yellow flowers in spring. Numerous cultivars are available as ornamental plants suitable for hedging.
Cornus alba is a species of flowering plant in the family Cornaceae, native to Siberia, northern China and Korea. It is a large surculose (suckering) shrub that can be grown as a small tree. As a popular ornamental used in landscaping its notable features include the red stems in fall (autumn) through late winter, the brightest winter bark of any cornus; and the variegated foliage in some cultivars, such as C. alba 'Elegantissima', in which the discreet flat whitish flower clusters are almost lost in the variegated texture and dappled light. C. alba can grow to 3 m (10 ft) high, but variegated forms are less vigorous. For the brightest winter bark, young shoots are encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open. The oval fruits are white, sometimes tinted blue.
Clerodendrum thomsoniae is a species of flowering plant in the genus Clerodendrum of the family Lamiaceae, native to tropical west Africa from Cameroon west to Senegal. It is an evergreen liana growing to 4 m (13 ft) tall, with ovate to oblong leaves 8–17 cm (3–7 in) cm long. The flowers are produced in cymes of 8-20 together, each flower with a pure white to pale purple five-lobed calyx 2.5 cm in diameter, and a red five-lobed corolla 2 cm long and in diameter.The flowers are born in cymose inflorescences arising from the axils of the leaves.The leaves, in turn, are arranged opposite to each other and at right angles to the pairs above and below.
Prostanthera rotundifolia, the roundleaf mint bush, is a species of flowering plant in the family Lamiaceae, one of about 90 Australian endemic species from the genus Prostanthera. Its native distribution is in South Australia, New South Wales, Victoria and Tasmania. The species is listed as vulnerable in Tasmania.

Growing to 3 m (10 ft) tall by 2.5 m (8 ft) wide, it is an upright deciduous shrub with dark green leaves turning red in autumn (fall). In midsummer, small lilac flowers are produced in the leaf axils. But it is grown in gardens primarily for its small, decorative purple berries in tight clusters in autumn. While the berries are not poisonous, they are very bitter. Wildlife will not eat them until there are no other available food sources. This species is more tolerant of cold than C. americana.

It is native to Southeast Asia but grown in many other places as a house plant. In warm regions, it is frequently grown outdoors on patios and in gardens rather than inside buildings, and hence it has escaped into the wild in Africa, Australia, South America, Mesoamerica, Florida, and a few other places.
