Roscoea Purpurea
''Roscoea purpurea'' is a perennial herbaceous plant occurring in the Himalayas, particularly Nepal. Most members of the ginger family ( Zingiberaceae), to which it belongs, are tropical, but species of ''Roscoea'' grow in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens. Description ''Roscoea purpurea'' is a perennial herbaceous plant. Like all members of the genus ''Roscoea'', it dies back each year to a short vertical rhizome, to which are attached the tuberous roots. When growth begins again, " pseudostems" are produced: structures which resemble stems but are actually formed from the tightly wrapped bases (sheaths) of its leaves. ''R. purpurea'' can grow to over 50 cm tall, with wide leaves and a stout pseudostem, although the height varies. The leaf sheaths are pale green or may have a dark reddish-purple tinge. The stem (peduncle) of the flower spike is hidden by the leaf sheaths. The flowers are the largest of any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Roscoe
William Roscoe (8 March 175330 June 1831) was an English banker, lawyer, and briefly a Member of Parliament. He is best known as one of England's first abolitionists, and as the author of the poem for children '' The Butterfly's Ball, and the Grasshopper's Feast''. In his day he was also respected as a historian and art collector, as well as a botanist and miscellaneous writer. Early life He was born in Liverpool, where his father, a market gardener, kept a public house called the Bowling Green at Mount Pleasant. Roscoe left school at the age of twelve, having learned all that his schoolmaster could teach. He assisted his father in the work of the garden, but spent his leisure time on reading and study. Later, he wrote: :This mode of life gave health and vigour to my body, and amusement and instruction to my mind; and to this day I well remember the delicious sleep which succeeded my labours, from which I was again called at an early hour. If I were now asked whom I consider t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...

Roscoea Purpurea Red Gurkha 060821
''Roscoea'' is a genus of perennial plants of the family Zingiberaceae (the ginger family). Most members of the family are tropical, whereas ''Roscoea'' species are native to mountainous regions of the Himalayas, China and its southern neighbours. ''Roscoea'' flowers superficially resemble orchids, although they are not related. The flowers of ''Roscoea'' have a complicated structure, in which some of the showy coloured parts are not formed by petals, but by staminodes, sterile stamens which have evolved to become like petals. Some species are grown as ornamental plants in gardens. Description ''Roscoea'' is found from Kashmir through the Himalayas to Vietnam, extending northwards into China. There are up to 22 recognized species, of which 8 are endemic to China. Typically they grow in grassland, in screes or on the edges of deciduous woodland at heights of , coming into growth at the start of the monsoon season. Species of ''Roscoea'' are small perennial herbaceous pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philoliche Longirostris
''Philoliche longirostris'' is a fly of the Tabanidae family that is found in India, Nepal specifically the Himalayas. It was first described and given a binomial name by Thomas Hardwicke in 1823. Description ''P. longirostris'' is especially notable by its proboscis, which is "many times longer than its body". Adults of the species in the Himalayas are said to emerge after the rains in July and are not seen after September. Their emergence matches the flowering of several species of '' Roscoea'' and it has been suggested that they may have coevolved with ''Philoliche''. Males and females feed on nectar using the long mouthparts formed by the prementum of the labium. Females, in addition, feed on blood using the mandibular and maxillary structures which are much shorter.

Terraced Walls
A terraced wall, also a terrace wall, or a terraced retaining wall is a wall that is divided into sections (Terrace (earthworks), terraces) over a slope. Such designs are useful when building on a steep Grade (slope), grade. Terraced walls may be built with many different building materials, materials. Some Impact crater, craters have terraced walls, which includes complex craters. Types of terraced walls A ''partially terraced wall'' is designed so that the upper terrace and lower terrace come back together, forming a taller wall. The wall may still work well, but may have Beauty , aesthetic issues. There are two types. In an ''independent terraced wall'', the upper wall applies little or no weight load on the lower wall. In a ''dependent terraced wall'', the upper wall places a weight load on the lower wall.
