Arboretum Park Härle
The Arboretum Park Härle (4.7 hectares) is a nonprofit arboretum located on the slopes of the Rhine Valley between Bonn and the Seven Mountains at Büchelstraße 40, Bonn, North Rhine-Westphalia, Germany. It is open twice a month during the warmer months; admission is free. The arboretum dates back to 1870, when the director of the ''Rheinische Eisenbahn-Gesellschaft'' created a large country house in the English half-timbered style, with park plantings that still remain, including two cedars (''Cedrus libani'' and ''Cedrus atlantica''), a ''Ginkgo biloba'', a ''Sequoiadendron'', and an incense cedar (''Calocedrus decurrens''). In 1921 the property was acquired by jurist Dr. Carl Härle, who actively planted a wide variety of trees and shrubs. After his death in 1950, his daughters Maria and Regina Härle maintained the property, and ultimately willed it to a nonprofit foundation in 2000. Today's arboretum consists of three distinct parts: the old park with old buildings, the ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arboreta In Germany
An arboretum (plural: arboreta) in a general sense is a botanical collection composed exclusively of trees of a variety of species. Originally mostly created as a section in a larger garden or park for specimens of mostly non-local species, many modern arboreta are in botanical gardens as living collections of woody plants and is intended at least in part for scientific study. In Latin, an ''arboretum'' is a place planted with trees, not necessarily in this specific sense, and "arboretum" as an English word is first recorded used by John Claudius Loudon in 1833 in ''The Gardener's Magazine'', but the concept was already long-established by then. An arboretum specializing in growing conifers is known as a pinetum. Other specialist arboreta include saliceta (willows), populeta ( poplar), and querceta (oaks). Related collections include a fruticetum, from the Latin ''frutex'', meaning ''shrub'', much more often a shrubbery, and a viticetum (from the Latin ''vitis,'' meaning vine ...

Rose
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. Etymology The name ''rose'' comes from L ...
