Aquilegia is a genus of about 60–70 species of perennial plants that are found in meadows, woodlands, and at higher altitudes throughout the Northern Hemisphere, known for the spurred petals of their flowers.
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.
Ranunculaceae is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide.
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.
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.
Aquilegia vulgaris is a species of columbine native to Europe with common names that include: European columbine, common columbine, granny's nightcap, and granny's bonnet. It is a flowering herbaceous perennial plant growing to 1.2 m tall, with branched, thinly hairy stems. The leaves are biternate; each leaf has three groups of three leaflets. The flowers, in various shades of purple, blue, pink and white, are pendent or horizontal with strongly hooked spurs, and appear in early summer.
The Victoria Medal of Honour (VMH) is awarded to British horticulturists resident in the United Kingdom whom the Royal Horticultural Society Council considers deserving of special honour by the Society.
Aquilegia chrysantha, the golden columbine, is a perennial herbaceous plant native to the southwestern United States from extreme southern Utah to Texas and northwestern Mexico.
Aquilegia bertolonii, common name Bertoloni columbine, is a species of flowering plant in the family Ranunculaceae, native to Southern France and Italy. Growing to 30 cm (12 in) in height, it is an alpine herbaceous perennial. In early summer each erect stem produces up to four spurred, blue-purple flowers.
Aquilegia flabellata, common name fan columbine or dwarf columbine, is a species of flowering perennial plant in the genus Aquilegia (columbine), of the family Ranunculaceae.
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.
Aquilegia alpina, the alpine columbine or breath of God, is a species of flowering plant in the family Ranunculaceae, native to the Alps, where it is typically found growing on carbonate bedrock.
Aquilegia viridiflora, commonly known as the green columbine or green-flowered columbine, is a species of flowering plant in the buttercup family. Its native range is southern Siberia to northern China, and Japan. It is an herbaceous perennial, and grows 15 cm to 50 cm tall, with a maximum spread of approximately 30 cm. Although it is grown as an ornamental, it may be considered a weed.
Aquilegia barnebyi, commonly known as the oil shale columbine or Barneby's columbine, is a perennial species of flowering plant in the buttercup family, with a native range comprising northeastern Utah and northwestern Colorado in the United States. It is named after Rupert Charles Barneby, who, with Harry Dwight Dillon Ripley, first discovered it in Colorado.
Kohleria hirsuta, the woolly kohleria, is a species of flowering plant in the family Gesneriaceae, native to northern South America, and introduced to the Dominican Republic. In 1993, as its synonym Kohleria eriantha, it gained the Royal Horticultural Society's Award of Garden Merit as a hothouse plant, but the award appears to have been recently revoked.
Aquilegia rockii is a species of flowering plant in the buttercup family with a native range comprising the WGSRPD floristic regions of South-Central China and Tibet, where it grows in forests. Plants grow 40-80cm tall, and produce flowers with purple or blue petals with spurs, which are either long or short. Longer spurs comprise a greater number of cells than shorter spurs; whether spurs are longer or shorter is determined through regulation of cell division rather than by plant growth substances.
Peronospora aquilegiicola is a species of oomycete in the family Peronosporaceae, first described in 2019. It is a plant pathogen: it can infect susceptible plants belonging to the genus Aquilegia, causing the plant disease Aquilegia downy mildew, as well as plants belonging to the genus Semiaquilegia. Peronospora aquilegiicola is native to East Asia, however it has a widespread distribution in the United Kingdom, and has since been detected in the German states of Lower Saxony, North Rhine-Westphalia, and Bavaria.
Aquilegia skinneri, commonly known as the Mexican columbine or Skinner's columbine, is a species of flowering plant in the buttercup family.
Aquilegia sibirica, commonly known as the Siberian columbine, is a species of flowering plant in the genus Aquilegia native to the north-central Asian regions of Siberia, northern Mongolia, Kazakhstan, and Xinjiang. A hardy perennial plant, it prefers temperate environments. The Siberian columbine can be between one and two feet tall with flowers that are lilac-blue and white in color.
