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 Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars.

Echeveria Perle Von Nurnberg
''Echeveria'' is a large genus of flowering plants in the family Crassulaceae, native to semi-desert areas of Central America, Mexico and northwestern South America. Description Plants may be evergreen or deciduous. Flowers on short stalks (cymes) arise from compact rosettes of succulent fleshy, often brightly coloured leaves. Species are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes. Often numerous offsets are produced, and are commonly known as "hen and chicks", which can also refer to other genera, such as ''Sempervivum'', that are significantly different from ''Echeveria''. Many species of ''Echeveria'' serve important environmental roles, such as those of host plants for butterflies. For example, the butterfly ''Callophrys xami'' uses several species of ''Echeveria'', such as ''Echevelia gibbiflora'', for suitable host plants. Even more, these plants are integral to the oviposition process of ''C. xami'' and some other but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Award Of Garden Merit Tulips
The following is a list of tulip species and cultivars which have gained the Royal Horticultural Society's Award of Garden Merit. They are bulbous perennial plant, perennials, originally from sunny, open habitats in Europe and Asia. Thousands of cultivars are available in a huge range of sizes, shapes and colours (other than pure blue). They are usually sold as bulbs to be planted in autumn and winter for flowering in mid- to late spring. They are frequently treated as bedding (horticulture), bedding plants, accompanied by other seasonal favourites such as Erysimum, wallflowers and forget-me-nots, flowering for one season before being discarded. However, in favoured locations they can be left in the ground to re-appear the following and subsequent years. Like many other bulbous plants they require a hot, dry dormant period in the summer. Groups Tulips are divided into 15 distinct groups:- #Single early - cup-shaped flowers to in diameter, often margined with contrasting colour; ear ...

List Of Award Of Garden Merit Rhododendrons
The following is a list of rhododendron cultivars and species which have gained the Royal Horticultural Society's Award of Garden Merit. They are mostly hardy evergreen shrubs with abundant, brilliantly-coloured, trumpet-shaped flowers, often in large spherical trusses. The group known as azaleas are often (but not always) more compact with smaller flowers and leaves, and may be evergreen (subgenus '' Tsutsuji'') or deciduous (subgenus '' Pentanthera''). Most rhododendrons bloom for a short period in late spring (April to May in the temperate Northern Hemisphere). They are seen at their best in a woodland setting with light dappled shade, in humus-rich acid soil. Maximum dimensions are shown in metres.

List Of Award Of Garden Merit Narcissus
Below is a selected list of ''Narcissus'' species, varieties and cultivars which currently (2020) hold the Royal Horticultural Society's Award of Garden Merit (AGM). Narcissus (daffodils) are bulbous perennials which are usually planted as dormant bulbs in autumn (fall) to flower the following spring. Once established they flower reliably every year, with variously trumpet-shaped flowers in a range of colours, mostly shades of white and yellow. The central trumpet (corona) and the outer 'petals' (perianth segments) often have contrasting colours. Breeders have produced a huge range of sizes and shapes in these flowers, which are among the most popular of all plants in cultivation. Divisions Plants are grouped by the RHS into 13 divisions, each describing a particular growth habit and flower shape. All are of garden origin except group 13. # Trumpet Daffodil cultivars: solitary flower with corona (trumpet) longer than perianth (outer petals) # Large-cupped Daffodil cultivars: co ...

List Of Award Of Garden Merit Maples
The maples belong to the genus ''Acer'', an important group of mainly deciduous trees and shrubs in the family Sapindaceae, which are widely cultivated throughout the temperate northern hemisphere. Some, such as ''Acer griseum'', have ornamental bark; but most are valued in cultivation for their brilliant autumn foliage in shades of yellow, orange and red. A vast number of cultivars have been developed for garden use. The palmate maple ''Acer palmatum'' alone has thousands of cultivars, many of which originate in Japan where the plant is especially prized for its compact size and elegant domed shape. Many maple species lend themselves to bonsai treatment. All tolerate a range of growing conditions, but prefer a partially shaded, sheltered position in soil that is well-drained but also retains moisture. Most are reasonably hardy down to or so.

List Of Award Of Garden Merit Magnolias
Below is a list of magnolia species and cultivars which currently (2016) hold the Royal Horticultural Society's Award of Garden Merit. Magnolias are shrubs or trees which put on a showy display of tulip-like flowers, often scented, in early to late spring. Many are slow-growing and may take several years to start flowering. They are suitable for cultivation in parks or gardens in temperate regions. ''M. stellata'' is suitable for smaller gardens. All are deciduous except for ''M. grandiflora'', which is evergreen.

List Of Award Of Garden Merit Dahlias
The following is a list of dahlia cultivars which have gained the Royal Horticultural Society's Award of Garden Merit. They are tuberous perennials, originally from South America, with showy daisy-like composite flowerheads in all shades and combinations of white, yellow, orange, pink and red, flowering in late summer and autumn (fall). Much work has been done on the development of a range of flower shapes and sizes. They may be sold as dry tubers in Spring, and started off in heat before being planted out after all danger of frost has passed. Alternatively they can be purchased later in the season, in pots ready to flower. Dwarf bedding types are usually cultivated as annuals and discarded after flowering. In mild areas without penetrating frosts, mature plants can be overwintered in the garden; otherwise, they are lifted and stored in a frost free place. They are easily propagated from cuttings in Spring. Flower shapes can be divided into 14 main groups:- #single: less than - o ...
