A rose is either a woody perennial flowering plant of the genus Rosa, in the family Rosaceae, or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.
Rosa rugosa is a species of rose native to eastern Asia, in northeastern China, Japan, Korea and southeastern Siberia, where it grows on beach coasts, often on sand dunes. It should not be confused with Rosa multiflora, which is also known as "Japanese rose". The Latin word "rugosa" means "wrinkled", referring to the wrinkled leaves. Often used as an ornamental plant, it has become invasive in parts of Europe, North America and South America.
Hibiscus rosa-sinensis, known colloquially as Chinese hibiscus, China rose, Hawaiian hibiscus, rose mallow and shoeblack plant, is a species of tropical hibiscus, a flowering plant in the Hibisceae tribe of the family Malvaceae. It is widely cultivated as an ornamental plant in the tropics and subtropics, but its native range is Vanuatu.
Pyrus calleryana, also known as the Callery pear or Bradford pear, is a species of pear tree native to China and Vietnam, in the family Rosaceae. It is most commonly known for its cultivar 'Bradford' and its offensive odor, widely planted throughout the United States and increasingly regarded as an invasive species.
Dasiphora fruticosa is a species of hardy deciduous flowering shrub in the family Rosaceae, native to the cool temperate and subarctic regions of the northern hemisphere, often growing at high altitudes in mountains. Dasiphora fruticosa is still widely referenced in the horticultural literature under its synonym Potentilla fruticosa. Common names include shrubby cinquefoil, golden hardhack, bush cinquefoil, shrubby five-finger, widdy, kuril tea and tundra rose.
Allium vineale is a perennial, bulb-forming species of wild onion, native to Europe, northwestern Africa and the Middle East. The species was introduced in Australia and North America, where it has become an Invasive species.
Dianthus barbatus, the sweet William, is a species of flowering plant in the family Caryophyllaceae, native to southern Europe and parts of Asia. It has become a popular ornamental garden plant. It is a herbaceous biennial or short-lived perennial plant growing to 13–92 cm tall, with flowers in a dense cluster of up to 30 at the top of the stems. Each flower is 2–3 cm diameter with five petals displaying serrated edges. Wild plants produce red flowers with a white base, but colours in cultivars range from white, pink, red, and purple to variegated patterns. The exact origin of its English common name is unknown but first appears in 1596 in botanist John Gerard's garden catalogue. The flowers are edible and may have medicinal properties. Sweet William attracts bees, birds, and butterflies.
Rosa banksiae, common names Lady Banks' rose, or just Banks' rose, is a species of flowering plant in the rose family, native to central and western China, in the provinces of Gansu, Guizhou, Henan, Hubei, Jiangsu, Sichuan and Yunnan, at altitudes of 500–2,200 m (1,640–7,218 ft). The rose is named for Dorothea Lady Banks, the wife of the botanist Sir Joseph Banks.
Hemerocallis fulva, the orange day-lily, tawny daylily, corn lily, tiger daylily, fulvous daylily, ditch lily or Fourth of July lily, is a species of daylily native to Asia. It is very widely grown as an ornamental plant in temperate climates for its showy flowers and ease of cultivation. It is not a true lily in the genus Lilium, but gets its common name from the superficial similarity of its flowers to Lilium and from the fact that each flower lasts only one day.
Ligustrum sinense is a species of privet native to China, Taiwan and Vietnam, and naturalized in Réunion, the Andaman Islands, Norfolk Island, Costa Rica, Honduras, Panamá and much of the eastern and southern United States. The name "Chinese privet" may also refer to Ligustrum lucidum.
Euonymus fortunei, the spindle, Fortune's spindle, winter creeper or wintercreeper, is a species of flowering plant in the family Celastraceae, native to east Asia, including China, Korea, the Philippines and Japan. E. fortunei is highly invasive and damaging in the United States, causing the death of trees and forest in urban areas.

Sedum spathulifolium is a species of flowering plant in the family Crassulaceae known by the common names broadleaf stonecrop, yellow stonecrop, and spoon-leaved stonecrop. An evergreen perennial, it is native to western North America from British Columbia to southern California, where it can be found often in shade in many types of rocky habitat in coastal and inland hills and mountains.
Garden roses are predominantly hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars have been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging.
Rosa 'Cécile Brünner', also known as 'Mlle Cécile Brünner', 'Sweetheart Rose', 'Malteser Rose', or 'Mignon', is a light pink polyantha rose bred in France by Marie Ducher and introduced by her son-in-law, Joseph Pernet-Ducher in 1881. Its parents were a double-flowered R. multiflora and a hybrid tea rose, either 'Souvenir d'un Ami' or a seedling of 'Mme de Tartas'. It is not clear if the rose was named after the sister (1853–1927) or daughter of Ulrich Brunner fils.
