The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity.
Horticulture is the art of cultivating plants in gardens to produce food and medicinal ingredients, or for comfort and ornamental purposes. Horticulturists are agriculturists who grow flowers, fruits and nuts, vegetables and herbs, as well as ornamental trees and lawns.
John Lindley FRS was an English botanist, gardener and orchidologist.
Grevillea, commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus Grevillea are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds.
Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand.
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.
Kerria japonica, commonly known as Japanese rose or Japanese kerria, Japanese ヤマブキ Yamabuki ) Chinese 棣(棠花) Dì (is a deciduous shrub in the rose family Rosaceae, native to China, Japan and Korea. It is named after William Kerr, who introduced the cultivar 'Pleniflora'. It is the sole species in the genus Kerria.
The Plant Review, published quarterly by the Royal Horticultural Society, is a 68-page magazine containing "fascinating in-depth articles for everyone who loves plants". Its authoritative articles are written by acknowledged experts on plant-related subjects, and include plant profiles, horticulture, botany and the development of garden plants, focusing on ornamental plants grown in temperate gardens. It also reflects the scientific work of the RHS, as well as research conducted by other horticultural and botanical institutions and individuals. First published in 1979 as The Plantsman, it was renamed The Plant Review from September 2019.
Juniperus squamata, the flaky juniper, or Himalayan juniper is a species of coniferous shrub in the cypress family Cupressaceae, native to the Himalayas and China.
Cornus alba, the red-barked, white or Siberian dogwood, is a species of flowering plant in the family Cornaceae, native to Siberia, northern China and Korea. It is a large deciduous surculose (suckering) shrub that can be grown as a small tree. As a popular ornamental used in landscaping its notable features include the red stems in fall (autumn) through late winter, bright winter bark; and the variegated foliage in some cultivars, such as C. alba 'Elegantissima'. C. alba can grow to 3 m (10 ft) high, but variegated forms are less vigorous. For the brightest winter bark, young shoots are encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open. The oval fruits are white, sometimes tinted blue.
RHS Garden Hyde Hall is a public display garden run by the Royal Horticultural Society in the English county of Essex. It is one of five public gardens run by the society, alongside Wisley in Surrey, Harlow Carr in North Yorkshire, Rosemoor in Devon, and Bridgewater in Greater Manchester.
Symphyotrichum ericoides, known as white heath aster, frost aster, or heath aster, is a species of flowering plant in the family Asteraceae native to much of central and eastern North America. It has been introduced to parts of Europe and western Asia.
Symphyotrichum novi-belgii, commonly called New York aster, is a species of flowering plant. It is the type species for Symphyotrichum, a genus in the family Asteraceae, whose species were once considered to be part of the genus Aster. Plants in both these genera are popularly known as Michaelmas daisy because they bloom around September 29, St. Michael’s Day.
Symphyotrichum pilosum, commonly called hairy white oldfield aster or frost aster, is a flowering plant in the family Asteraceae native to central and eastern North America. It is a perennial, herbaceous plant that may reach 20 to 120 centimeters tall. Its flowers have white ray florets and yellow disk florets.
Roderick Leon Bieleski was a New Zealand plant physiologist. As a botanist and horticulturist, his research focussed on understanding the factors that affected the behaviour of plants, in particular horticultural crops. His work had practical relevance to farmers and orchardists in building their understanding of these factors and taking account of them while making a living from growing and harvesting plants. He received many honours and awards, culminating in being appointed Member of the New Zealand Order of Merit (MNZM) in 2010.
Eriocapitella × hybrida is a hybrid of flowering plants in the buttercup family Ranunculaceae. The parents of the hybrid are E. japonica and E. vitifolia. Cultivars of the hybrid are commonly known as Japanese anemone hybrids.
Genista sagittalis, called the arrow-jointed broom and winged broom, is a species of flowering plant in the genus Genista, native to central and southern Europe, Ukraine, and Anatolia. Its subspecies Genista sagittalis subsp. delphinensis, called rock broom, has gained the Royal Horticultural Society's Award of Garden Merit.
Parodia concinna, the sun cup, is a species of cactus in the genus Parodia, native to southern Brazil and Uruguay. It has gained the Royal Horticultural Society's Award of Garden Merit.
Euonymus oxyphyllus, the Korean spindle tree, is a species of flowering plant in the family Celastraceae, native to central and eastern China, Manchuria, Korea, Japan and the Kurils. It is a shrub or small tree typically reaching 2.5 m (8 ft). The Royal Horticultural Society considers it to be a good tree for smaller gardens, especially for its colorful Autumn foliage and fruits.
