Arboretum National Des Barres
The Arboretum national des Barres (35 hectares) is a national arboretum located in Nogent-sur-Vernisson, Loiret, Centre-Val de Loire, France. It is open daily in the warmer months; an admission fee is charged. Closure is planned for the end of year 2018 because subsidy from local and national government is too short. The Domaine des Barres (283 hectares) was purchased in 1821 by Philippe André de Vilmorin for his studies in forestry. At that time it was almost entirely barren of trees, but Vilmorin planted today's extensive forest, primarily of ''Pinus sylvestris'', '' P. laricio'', and '' P. pinaster'', as well as American oaks. In 1866 his heirs sold 67 hectares to the nation, on which was established a forestry school, and in 1873 Constant Gouet, the arboretum's first director, began the geographic collection on 3 hectares. The Vilmorin family continued to be actively involved, particularly Maurice de Vilmorin, whose shrub collection was given to the state in 1921 following h ...

Arboretum Barres
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 vin ...

Spruce
A spruce is a tree of the genus ''Picea'' (), a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Earth. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine family by their needles (leaves), which are four-sided and attached singly to small persistent peg-like structures (pulvini or sterigmata) on the branches, and by their cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species, such as the eastern spruce budwo ...

Arboretum Vilmorin
The Arboretum Vilmorin (4 hectares) is a private arboretum located at 2 rue d'Estienne d'Orves, Verrières-le-Buisson, Essonne, Île-de-France, France. It is open by appointment only. A newer portion of the family arboretum was acquired by the municipality in 1975, and is now open to the public as the Arboretum municipal de Verrières-le-Buisson. The arboretum is located on the site of a former hunting lodge of Louis XIV of France, acquired in 1815 by Philippe-André de Vilmorin (1776-1862), who also began today's Arboretum national des Barres in 1821. He transformed the lodge's grounds into a collection of trees and shrubs from around the world as missionaries and explorers sent specimens from the Far East, America, North Africa, Siberia, and the Caucasus. Plans for the arboretum walls are attributed to André Le Nôtre. Today's arboretum has been tended by seven generations of the Vilmorin family, assisted in recent years by a scientific committee. At present the arboretum conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arboretum De Pézanin
The Arboretum de Pézanin or Arboretum Domanial de Pézanin (''Federal Arboretum of Pézanin'') is an arboretum located in Dompierre-les-Ormes, Saône-et-Loire, Bourgogne, France. It is one of the oldest and richest forest collections in France, with trees and plants from all around the world. History The arboretum was established in 1903 by the famous French botanist Philippe de Vilmorin (1872-1917), ''seigneur'' of Audour. He created the arboretum around the lake on his estate at Pézanin. Between 1903 and 1923, over 1100 species were planted, mainly from North America and Asia. After that, it fell into a period of abandonment until it was acquired by the state in 1935. It is now owned by the French Ministry of Agriculture and managed by the '' Office national des Forêts (ONF)''. Although the arboretum was damaged by storms in 1981 and 1999, it has recently undergone renewed plantings. Today it contains more than 450 species of trees, with walking paths and a pond. There ...

Juniper
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of West Asia, western, Central Asia, central and South Asia, southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female Conifer cone, seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form Juniper berry, a&n ...

Metasequoia
''Metasequoia'', or dawn redwoods, is a genus of fast-growing deciduous trees, one of three species of pinophyta, conifers known as redwoods. The living species ''Metasequoia glyptostroboides'' is native to Lichuan, Hubei, Lichuan county in Hubei province, China. Although the shortest of the Sequoioideae, redwoods, it grows to at least in height. Local villagers refer to the original tree from which most others derive as ''Shuǐshān'' (水杉）, or "water fir", which is part of a local shrine. Since its rediscovery in 1944, the dawn redwood has become a popular ornamental, with examples found in various parks in a variety of countries. Together with ''Sequoia sempervirens'' (coast redwood) and ''Sequoiadendron giganteum'' (giant sequoia) of California, ''Metasequoia'' is classified in the Cupressaceae subfamily Sequoioideae. ''M. glyptostroboides'' is the only living species in its genus, but three fossil species are known. Sequoioideae and several other genera have been ...

Beech
Beech (''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, ''Engleriana'' and ''Fagus''. The ''Engleriana'' subgenus is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known ''Fagus'' subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech (''Fagus sylvatica'') is the most commonly cultivated. Beeches are monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small burrs that drop from the tree in autumn. They are small, roughly triangular, and edible, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wisteria
''Wisteria'' is a genus of flowering plants in the legume family, Fabaceae (Leguminosae), that includes ten species of woody twining vines that are native to China, Japan, Korea, Vietnam, Southern Canada, the Eastern United States, and north of Iran. They were later introduced to France, Germany and various other countries in Europe. Some species are popular ornamental plants. The aquatic flowering plant commonly called wisteria or 'water wisteria' is in fact ''Hygrophila difformis'', in the family Acanthaceae. Etymology The botanist Thomas Nuttall said he named the genus ''Wisteria'' in memory of the American physician and anatomist Caspar Wistar (1761–1818). Both men were living in Philadelphia at the time, where Wistar was a professor in the School of Medicine at the University of Pennsylvania. Questioned about the spelling later, Nuttall said it was for "euphony", but his biographer speculated that it may have something to do with Nuttall's friend Charles Jones Wister S ...

Magnolia
''Magnolia'' is a large genus of about 210 to 340The number of species in the genus ''Magnolia'' depends on the taxonomic view that one takes up. Recent molecular and morphological research shows that former genera ''Talauma'', ''Dugandiodendron'', ''Manglietia'', ''Michelia'', ''Elmerrillia'', ''Kmeria'', ''Parakmeria'', ''Pachylarnax'' (and a small number of monospecific genera) all belong within the same genus, ''Magnolia'' s.l. (s.l. = ''sensu lato'': 'in a broad sense', as opposed to s.s. = ''sensu stricto'': 'in a narrow sense'). The genus ''Magnolia'' s.s. contains about 120 species. See the section Nomenclature and classification in this article. flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. ''Magnolia'' is an ancient genus. Appearing before bees evolved, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpe ...

Davidia Involucrata
''Davidia involucrata'', the dove-tree, handkerchief tree, pocket handkerchief tree, or ghost tree, is a medium-sized deciduous tree in the family Nyssaceae. It is the only living species in the genus ''Davidia''. It was previously included with tupelos in the dogwood family, Cornaceae. Fossil species are known extending into the Upper Cretaceous. Taxonomy ''Davidia involucrata'' is the only member of its genus, but there are two varieties differing slightly in their leaves, ''D. involucrata'' var. ''involucrata'', which has the leaves thinly pubescent (short-haired) on the underside, and ''D. involucrata'' var. ''vilmoriniana'', with glabrous (hairless) leaves. Some botanists treat them as distinct species, with good reason, as the two taxa have differing chromosome numbers so are unable to produce fertile hybrid offspring. Description It is a moderately fast-growing tree, growing to in height, with toothed, alternate, ovate-cordate leaves resembling those of a linden, exce ...

Azalea
Azaleas are flowering shrubs in the genus ''Rhododendron'', particularly the former sections ''Tsutsusi'' (evergreen) and '' Pentanthera'' (deciduous). Azaleas bloom in the spring (April and May in the temperate Northern Hemisphere, and October and November in the Southern Hemisphere), their flowers often lasting several weeks. Shade tolerant, they prefer living near or under trees. They are part of the family Ericaceae. Cultivation Plant enthusiasts have selectively bred azaleas for hundreds of years. This human selection has produced over 10,000 different cultivars which are propagated by cuttings. Azalea seeds can also be collected and germinated. Azaleas are generally slow-growing and do best in well-drained acidic soil (4.5–6.0 pH). Fertilizer needs are low. Some species need regular pruning. Azaleas are native to several continents including Asia, Europe and North America. They are planted abundantly as ornamentals in the southeastern US, southern Asia, and parts o ...
