The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity.
Horticulture is the cultivation of plants in gardens or greenhouses, as opposed to the field-scale production of crops characteristic of agriculture. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns.
Lathyrus latifolius, the perennial peavine, perennial pea, broad-leaved everlasting-pea, or just everlasting pea, is a robust, sprawling herbaceous perennial flowering plant in the pea family Fabaceae. It is native to Europe but is present on other continents, such as North America and Australia, where it is most often seen along roadsides.
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.
Nephrolepis exaltata, known as the sword fern or Boston fern, is a species of fern in the family Lomariopsidaceae. It is native to the Americas. This evergreen plant can reach as high as 40–90 centimetres (16–35 in), and in extreme cases up to 1.5 metres. It is also known as the Boston sword fern, wild Boston fern, Boston Blue Bell Fern, tuber ladder fern, or fishbone fern.
Tagetes patula, the French marigold, is a species of flowering plant in the family Asteraceae, native to Mexico and Guatemala with several naturalised populations in many other countries. It is widely cultivated as an easily grown bedding plant, with thousands of different cultivars in brilliant shades of yellow and orange.
Weigela is a genus of between six and 38 species of deciduous shrubs in the family Caprifoliaceae, growing to 1–5 m (3–15′) tall. All are natives of eastern Asia. The genus is named after the German scientist Christian Ehrenfried Weigel.
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.
Berberis verruculosa, the warty barberry or warted barberry, is an evergreen shrub, ranging in size from 1–2 m, native to western China. It gets its common name from its "warty" stems, that have rounded, more or less identical, raised spots.
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.
Lilium pardalinum, also known as the leopard lily or panther lily, is a flowering bulbous perennial plant in the lily family, native to Oregon, California, and Baja California. It usually grows in damp areas. Its range includes California chaparral and woodlands habitats and the Sierra Nevada.
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.
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.
Faucaria is a genus of around 8 species of succulent subtropical flowering plants of the family Aizoaceae. The name comes from the Latin word fauces because of the appearance of "teeth" on the leaves.
Faucaria felina, tiger jaws, is a species of succulent plant in the family Aizoaceae. It is endemic to the southern Cape Provinces of South Africa, but also widely spread in culture. It has a clumping habit and blooms with yellow flowers. As its synonym Faucaria candida, white tiger jaws, it has gained the Royal Horticultural Society's Award of Garden Merit.
Faucaria tigrina, tiger jaws, is a species of succulent plant in the family Aizoaceae. It is endemic to South Africa, but also widely spread in cultivation. It has fleshy triangular leaves, a clumping habit, and blooms in autumn with yellow daisy-like flowers.
Symphyotrichum turbinellum, commonly called prairie aster in the United States and mauve-flowered starwort in the United Kingdom, is a species of flowering plant in the family Asteraceae native to the United States in Arkansas, Illinois, Iowa, Kansas, Louisiana, Missouri, Nebraska, and Oklahoma, primarily in the Ozarks. It has gained the Royal Horticultural Society's Award of Garden Merit.
Lindera praecox, the February spicebush, is a species of flowering plant in the family Lauraceae, native to southern China, and Japan. A deciduous shrub typically 4.5 to 7.5 m tall, it is hardy to USDA Zone 8. In the wild it is found in thickets on the slopes of hills and mountains, and on the banks of streams and lakes. It is occasionally available from specialty nurseries.
