Ventnor Botanic Garden
Ventnor Botanic Garden is a botanic garden located in Ventnor, Isle of Wight. It was founded in 1970, by Sir Harold Hillier, and donated to the Isle of Wight Council. Its collection comprises worldwide temperate and subtropical trees and shrubs organised by region. The garden's unusual climate is more akin to the Mediterranean and enables a wide variety of plants considered too tender for much of mainland Britain to be grown. These grow in the open air, and benefit from the moist and sheltered microclimate of the south-facing Undercliff landslip area on the Isle of Wight coast. When frost does occur it is usually of short duration and not of great severity. History The garden is on the site of the Royal National Hospital for Diseases of the Chest, a sanatorium established there to exploit the same mild climate. Founded by Arthur Hill Hassall, designed by local architect Thomas Hellyer and opened in 1869 as the National Cottage Hospital for Consumption and Diseases of the Chest ...

Deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of ''deciduous'' in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called ...

Sir Harold Hillier Gardens
The Sir Harold Hillier Gardens is an arboretum comprising 72 hectares (180 acres) accommodating over 42,000 trees and shrubs in about 12,000 taxa, notably a collection of oaks, camellia, magnolia and rhododendron. The Gardens are located northeast of the town of Romsey in Hampshire, England, and were formerly known simply as the Hillier Arboretum, founded by nurseryman Harold Hillier in June 1953 when he acquired Jermyn's House and its grounds. The arboretum was given to Hampshire County Council in 1977 to be managed as a charitable trust. Sir Harold Hillier was knighted in 1983, just two years before his death at age 80 in 1985. The Gardens were listed as Grade II on the National Register of Historic Parks and Gardens in 1997. Organisation Run as a registered charity, the Gardens are continually developed to further Sir Harold’s philosophy of horticulture, conservation, education and recreation. The president of the trust is the Duchess of Cornwall and the patrons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aldenham House
Aldenham House is a former country house in Elstree, just south-east of Aldenham village and west of Borehamwood, Hertfordshire, England, which was the seat of the Gibbs family, who were the Barons Aldenham. The site today accommodates the Hilfield Reservoir, the Lister Institute, the Haberdashers' Boys' School and Haberdashers' School for Girls. The house was built c.1672 for H. Coghill the Younger and was acquired, renovated and extended c.1870 by the wealthy Hucks Gibbs, 1st Baron Aldenham. In 1932 the estate was sold after the death of its then occupant Vicary Gibbs, a wealthy financier, MP and avid plant collector who had amassed a larger collection of Chinese flora than the Royal Botanic Gardens Kew. Gibbs never married, and most of the plant collection was auctioned after his death.Audrey Le Lievre (1986).

Borde Hill
Borde Hill Garden is a garden located north of Haywards Heath, West Sussex in southern England. It is set in over of garden, park and woodlands which has views across the Sussex High Weald. Borde Hill Garden is planted in “living garden rooms”, each offering a different character and style. It is home to many rare shrubs: from rhododendrons, azaleas and magnolias to roses, as well as numerous trees including one of the largest collections of champion trees in a private property in Britain (82 specimens as of 2013). History The first record of the estate dates back to 1534. The Tudor Borde Hill house was originally constructed in 1598 by Stephen Borde. After a variety of ownerships, Borde Hill was acquired by Colonel Robert Stephenson Clarke in 1893, who was the first owner to plant the gardens and woodlands. A number of extensions were made to the garden and house, however it was not until 1965 that Borde Hill Garden became a registered charity and opened to the publ ...

Diameter At Breast Height
Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Tree trunks are measured at the height of an adult's breast, which is defined differently in different countries and situations. In many countries, DBH is measured at approximately above ground. Global variation and scientific precision The height can make a substantial difference to the measured diameter. In the United States, DBH is typically measured at above ground. In some countries, such as Australia, New Zealand, Burma, India, Malaysia, and South Africa, breast height diameter has historically been measured at a height of , but because of much active research into allometrics that are being applied to trees and forests, the convention of is more appropriate. Ornamental trees are usually measured at 1.5 metres above ground. Some authors have argued that the term DBH should be abol ...

Thorp Perrow Arboretum
Thorp Perrow Arboretum is an woodland garden arboretum near Bedale in North Yorkshire, England. History Thorp is a common place-name of Old Norse origin meaning hamlet or small village. In the Domesday Book of 1086 Thorp was a possession of Count Alan of Brittany. Perrow derives from the lords of the manor of Pirnhow (also written Pirhou or Pirho) in Norfolk, who were the earliest known tenants here. In 1286-87 Helewise de Perrow was a tenant. There is no surviving record of a village at Thorp Perrow. A park called Thorpe Park went with the manor of Thorp Perrow in the 16th and 17th centuries. Spring Wood was planted in the 16th century, and survives to this day. Thorp Perrow Hall was built in the early 18th century. Ornamental gardens and lakes were laid out around 1800, and a collection of exotic conifers called Milbank Pinetum was planted between 1840 and 1870 by Lady Augusta Milbank. The Arboretum was originally created by Colonel Sir Leonard Ropner (1895–1977) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernest Henry Wilson
Ernest Henry "Chinese" Wilson (15 February 1876 – 15 October 1930), better known as E. H. Wilson, was a notable British plant collector and explorer who introduced a large range of about 2000 Asian plant species to the West; some sixty bear his name. Career Wilson was born in Chipping Campden, Gloucestershire but the family soon moved to Shirley, Warwickshire, where they set up a floristry business. He left school early for employment at the local nursery of Messrs. Hewitt, Warwickshire, as apprentice gardener, and, aged 16, at the Birmingham Botanical Gardens; there he also studied at Birmingham Municipal Technical School in the evenings, receiving the Queen's Prize for botany. In 1897 he began work at the Royal Botanic Gardens, Kew, where he won the Hooker Prize for an essay on conifers. He then accepted a position as Chinese plant collector with the firm of James Veitch & Sons, who were eager above all to retrieve the dove tree, '' Davidia involucrata''. "Stick to the ...

Ploidy
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Cyme (botany)
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk i ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses ( Poaceae ...

Augustine Henry
Augustine Henry (2 July 1857 – 23 March 1930) was a British-born Irish plantsman and sinologist. He is best known for sending over 15,000 dry specimens and seeds and 500 plant samples to Kew Gardens in the United Kingdom. By 1930, he was a recognised authority and was honoured with society membership in Belgium, Czechoslovakia, Finland, France, and Poland. In 1929 the Botanical Institute of Peking dedicated to him the second volume of ''Icones plantarum Sinicarum'', a collection of plant drawings. In 1935, ''John William Besant'' was to write: 'The wealth of beautiful trees and flowering shrubs which adorn gardens in all temperate parts of the world today is due in a great measure to the pioneer work of the late Professor Henry'.Besant, J. W. (1935) 'Plantae Henryanae', ''Gard. Chron.'' 98 (9 November 1935): 334–335. Early life and education Henry was born on 2 July 1857 in Dundee, Scotland to Bernard (a flax merchant) and Mary (née McManee) Henry; the family returned to ...
