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.
Stipa is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to Stipa, which have since been reclassified into new genera.
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.
Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons.

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.
Nassella tenuissima is a species of grass known by the common names Mexican feathergrass, finestem needlegrass, fineleaved nassella, and Argentine needle-grass. It is native to the south-western United States, northern Mexico and Argentina. It is well-matched to climate in Australia and can be harmful to the Australian environment.
Stipa lessingiana, called Lessing feather grass, is a species of flowering plant in the genus Stipa, found in steppes from Greece east to Mongolia, including the countries bordering the Black and Caspian Seas, Central Asia, western Siberia, the Altai, and Xinjiang in China. It has gained the Royal Horticultural Society's Award of Garden Merit.
Jarava plumosa is a species of grass in the family Poaceae, native to the Southern Cone of South America. It has been introduced to other places with a Mediterranean climate; California, Spain, Israel, the Cape Provinces of South Africa, and South Australia. As its synonym Stipa papposa it has gained the Royal Horticultural Society's Award of Garden Merit as an ornamental in spite of its invasive potential.
Nassella charruana, the lobed needle grass, is a species of bunchgrass in the family Poaceae, native to southern Brazil, Uruguay, and northeastern Argentina, and introduced to Victoria, Australia.
