Garden roses
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. Numerous 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, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging. It is believed that roses were grown in all the early civilisations of temperate latitudes from at least 5000 years ago.
Rose
A rose is a woody perennial flowering plant of the genus Rosa, in the family Rosaceae, or the flower it bears. There are over a hundred species and 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. 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.
Thousand-year Rose
The Thousand-year Rose (German: Tausendjähriger Rosenstock, literally: Thousand-years rosebush) is also known as the Rose of Hildesheim. It grows on a wall of the Hildesheim Cathedral, a Catholic cathedral in Hildesheim, Germany, that is dedicated to the Assumption of Mary. The cathedral and the adjacent St. Michael's Church have been on the UNESCO list of World Heritage Sites since 1985. The rose that climbs on the wall of the cathedral's apse is believed to be the oldest living rose in the world. A "Rosa canina", commonly known as a wild dog rose, it grows against the eastern apse of the cathedral, which is around high and wide.
The Rose Rent
The Rose Rent is a medieval mystery novel set in the summer of 1142 by Ellis Peters. This is the thirteenth novel in The Cadfael Chronicles, first published in 1986 (1986 in literature). It was adapted for television in 1997 by Carlton and Central for ITV. A young monk is murdered next to a white rose bush at a home bequeathed to the Abbey by a young widow. Brother Cadfael finds the murderer as the widow makes peace with her loss. Shrewsbury Abbey anticipates two events coming on 22 June in 1142: honouring the day five years earlier when Saint Winifred's reliquary was placed on its altar, and paying the rent due to the widow Judith Perle.
Rosa banksiae
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 . It is a scrambling shrubby vine growing vigorously to tall. Unlike most roses, it is practically thornless, though it may bear some prickles up to 5 mm long, particularly on stout, strong shoots. The leaves are evergreen, 4–6 cm long, with three to five (rarely seven) leaflets 2–5 cm long with a serrated margin. The flowers are small, 1.5–2.5 cm diameter, white or pale yellow.
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop.
Podosphaera pannosa
Podosphaera pannosa is a plant pathogen. It produces a powdery mildew on members of the rose family. Rose powdery mildew [also known as 'Weeping Mildred'] is caused by the fungus "Podosphaera pannosa", a member of the Ascomycete fungi. It infects a wide variety of roses, but especially those grown in dryer climates as the fungus has the rare characteristic that not only does it not need water to germinate and reproduce, it can be inhibited by it. The disease cycle of rose powdery mildew starts when the sexual spores, ascospores, of the pathogen survive the winter in a structure composed of hyphae called an ascocarp.
