Cassop Vale
Cassop Vale is a Site of Special Scientific Interest in the Durham City district of County Durham, England. It lies between the villages of Bowburn and Cassop, 7 km south-east of the centre of Durham.. The site is important as one of the larger areas of grassland developed on magnesium limestone. This rock has a restricted distribution in England and grassland associated with it is confined almost entirely to south-east Tyneside and County Durham, usually in small, scattered patches that are threatened by quarrying and modern agricultural practices. Habitats at Cassop Vale include grassland, scrub, woodland and wetland, the last fed by spring-lines. The area also includes recolonised open quarries and mine spoil-heaps, which add to the floral diversity. The main grass species on the magnesian limestone is blue moor-grass ''Sesleria albicans'' amongst which grow fragrant orchid ''Gymnadenia conopsea'', cowslip, ''Primula veris'', rock rose ''Helianthemum nummularium'', an ...

Durham, England
Durham ( , locally ) is a cathedral city and civil parish in the county of Durham, England. It is the county town and contains the headquarters of Durham County Council, the unitary authority which governs the district of County Durham. It had a population of 48,069 at the 2011 Census. The city was built on a meander of the River Wear, which surrounds the centre on three sides and creates a narrow neck on the fourth. The surrounding land is hilly, except along the Wear's floodplain to the north and southeast. Durham was founded in 995 by Anglo-Saxon monks seeking a place safe from Viking raids to house the relics of St Cuthbert. The church the monks built lasted only a century, as it was replaced by the present Durham Cathedral after the Norman Conquest; together with Durham Castle it is a UNESCO World Heritage Site. From the 1070s until 1836 the city was part of the County Palatine of Durham, a semi-independent jurisdiction ruled by the bishops of Durham which acted as a buf ...

Corylus Avellana
''Corylus avellana'', the common hazel, is a species of flowering plant in the birch family Betulaceae. It is native to Europe and western Asia. It is an important component of the hedgerows that were the traditional field boundaries in lowland England. The wood was traditionally grown as coppice, the poles cut being used for wattle-and-daub building and agricultural fencing. Common hazel is cultivated for its nuts. The name hazelnut applies to the nuts of any species in the genus ''Corylus'', but in commercial settings a hazelnut is usually that of ''C. avellana''. This hazelnut or cob nut, the kernel of the seed, is edible and used raw or roasted, or ground into a paste. The cob is round, compared with the longer filbert nut. Description Common hazel is typically a shrub reaching tall, but can reach . The leaves are deciduous, rounded, long and across, softly hairy on both surfaces, and with a double-serrate margin. The flowers are produced very early in spring, before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulex Europaeus
''Ulex europaeus'', the gorse, common gorse, furze or whin, is a species of flowering plant in the family Fabaceae, native to the British Isles and Western Europe. Description Growing to tall, it is an evergreen shrub. The young stems are green, with the shoots and leaves modified into green spines, long. Young seedlings produce normal leaves for the first few months; these are trifoliate, resembling a small clover leaf. The solitary flowers are yellow, long, with the pea-flower structure typical of the Fabaceae; they are produced throughout the year, but mainly over a long period in spring. They are coconut-scented. The fruit is a legume (pod) long, dark purplish-brown, partly enclosed by the pale brown remnants of the flower; the pod contains 2–3 small blackish, shiny, hard seeds, which are ejected when the pod splits open in hot weather. Seeds remain viable for 30 years. Like many species of gorse, it is often a fire-climax plant, which readily catches fire but re-g ...

Crataegus Monogyna
''Crataegus monogyna'', known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world. Names This species is one of several that have been referred to as ''Crataegus oxyacantha'', a name that has been rejected by the botanical community as too ambiguous. In 1793, Medikus published the name ''C. apiifolia'' for a European hawthorn now included in ''C. monogyna,'' but that name is illegitimate under the rules of botanical nomenclature. Other common names include may, mayblossom, maythorn, (as the plant generally flowers in May in the English-speaking parts of Europe) quickthorn, whitethorn, motherdie, and haw. Description The common hawthorn is a shrub or small tree up to about tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear shar ...

Centaurea Nigra
''Centaurea nigra'' is a species of flowering plant in the family Asteraceae known by the common names lesser knapweed, common knapweed and black knapweed. A local vernacular name is hardheads. It is native to Europe but it is known on other continents as an introduced species and often a noxious weed. Although the plant is often unwanted by landowners because it is considered a weed by many, it provides a great deal of nectar for pollinators. It was rated in the top five for most nectar production (nectar per unit cover per year) in a UK plants survey. It also placed second as a producer of nectar sugar per floral unit, among the meadow perennials, in another study in Britain. Description It is a herbaceous perennial growing up to about a metre in height. The leaves are up to long, usually deeply lobed, and hairy. The lower leaves are stalked, whilst the upper ones are stalkless. The inflorescence contains a few flower heads, each a hemisphere of black or brown bristly ph ...
