Gentiana acaulis, the stemless gentian, or trumpet gentian, is a species of flowering plant in the family Gentianaceae, native to central and southern Europe, from Spain east to the Balkans, growing especially in mountainous regions, such as the Alps and Pyrenees, at heights of 800–3,000 m (2,625–9,843 ft).
Cymbidium, commonly known as boat orchids, is a genus of evergreen flowering plants in the orchid family Orchidaceae. Orchids in this genus are epiphytic, lithophytic, terrestrial or rarely leafless saprophytic herbs usually with pseudobulbs. There are usually between three and twelve leaves arranged in two ranks on each pseudobulb or shoot and lasting for several years. From one to a large number of flowers are arranged on an unbranched flowering stem arising from the base of the pseudobulb. The sepals and petals are all free from and similar to each other. The labellum is significantly different from the other petals and the sepals and has three lobes. There are about fifty-five species and sixteen further natural hybrids occurring in the wild from tropical and subtropical Asia to Australia. Cymbidiums are well known in horticulture and many cultivars have been developed. The genome of Cymbidium mannii has been sequenced to study epiphytism and crassulacean acid metabolism.
Osteospermum, is a genus of flowering plants belonging to the Calenduleae, one of the smaller tribes of the sunflower/daisy family Asteraceae. They are known as the daisybushes or African daisies. Its species have been given several common names, including African daisy, South African daisy, Cape daisy and blue-eyed daisy.
Cota tinctoria, the golden marguerite, yellow chamomile, or oxeye chamomile, is a species of perennial flowering plant in the sunflower family. Other common names include dyer's chamomile, Boston daisy, and Paris daisy. In horticulture this plant is still widely referred to by its synonym Anthemis tinctoria.
Anemonoides nemorosa, the wood anemone, is an early-spring flowering plant in the buttercup family Ranunculaceae, native to Europe. Other common names include windflower, European thimbleweed, and smell fox, an allusion to the musky smell of the leaves. It is a perennial herbaceous plant growing 5–15 cm (2–6 in) tall.
Iochroma is a genus of about 34 species of shrubs and small trees belonging to the nightshade family Solanaceae. Species are native from Mexico to south Brazil. They are found in the forests of Mexico and South America. Their hummingbird-pollinated flowers are tubular or trumpet-shaped, and may be blue, purple, red, yellow, or white, becoming pulpy berries. The cupular (cup-shaped) calyx is inflated in some species. The leaves are alternate, simple, and entire.
Sphaeropteris cooperi, synonym Cyathea cooperi, also known as lacy tree fern, scaly tree fern, or Cooper's tree fern, is a tree fern native to Australia, in New South Wales and Queensland.
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.
Baptisia australis, commonly known as blue wild indigo or blue false indigo, is a flowering plant in the family Fabaceae (legumes). It is a perennial herb native to much of central and eastern North America and is particularly common in the Midwest, but it has also been introduced well beyond its natural range. Naturally it can be found growing wild at the borders of woods, along streams or in open meadows. It often has difficulty seeding itself in its native areas due to parasitic weevils that enter the seed pods, making the number of viable seeds very low. The plant has low toxicity levels for humans.
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.
Cynoglossum amabile, the Chinese hound's tongue or Chinese forget-me-not, is a species of flowering plant in the family Boraginaceae, native to Asia. A hardy annual growing to 50 cm (20 in), it has hairy leaves and cymes of sky-blue flowers in late summer. This plant, closely related to the common forget-me-not of temperate gardens, is also grown as an ornamental. In cultivation in the UK it has gained the Royal Horticultural Society's Award of Garden Merit..
Bulbophyllum deshmukhii, synonym Genyorchis macrantha, is a species of plant in the family Orchidaceae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical dry forests.
Berberis oiwakensis is a species of plant in the barberry family, Berberidaceae. It is native to Taiwan, China and Myanmar, where it occurs at elevations of 600 to 3800 m. It has recently been found naturalized in South Africa.
Gentiana septemfida, the crested gentian or summer gentian, is a species of flowering plant in the family Gentianaceae, native to the Caucasus and Turkey. It is a low-growing herbaceous perennial growing to 15–20 cm (6–8 in) tall by 30 cm (12 in) wide, bearing up to eight bright blue trumpet-shaped blooms in summer, with striped interiors. It requires a rich, moist soil and full sun.
Argyranthemum frutescens, known as Paris daisy, marguerite or marguerite daisy, is a perennial plant known for its flowers. It is native to the Canary Islands. Hybrids derived from this species are widely cultivated as ornamental plants in private gardens and public parks in many countries, and have naturalized in Italy and southern California. There are many cultivars, but the most common has white petals.
Berberis japonica is a species of flowering plant in the family Berberidaceae, native to Taiwan. Despite the name, it is not native to Japan, though it has been known in cultivation there for centuries. The wild origins of this species have long puzzled botanists, but wild plants in Taiwan, previously known under the name Mahonia tikushiensis, appear most similar to the cultivated forms of B. japonica.
Scilla forbesii, known as Forbes' glory-of-the-snow, is a bulbous perennial plant from west Turkey flowering in early spring. It is considered synonymous with Scilla siehei, known as Siehe's glory-of-the-snow, by some sources, although others distinguish them. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa. After flowering, it goes into dormancy until the next spring. It seeds readily to form colonies.
The Field Elm cultivar Ulmus minor 'Dicksonii', commonly known as Dickson's Golden Elm, is a yellow-leaved tree raised in Chester in 1900 by Dickson's Nursery, which distributed it from the autumn of 1907 as 'Golden Cornish Elm'. 'Cornish Elm' was the name often given in error to Guernsey or Wheatley Elm by the local authorities who planted the latter extensively, an error which may have influenced the choice of name by Dickson's nursery. 'Dicksonii' is usually listed as a variety of Guernsey Elm rather than Cornish Elm, Bean giving 'Wheatleyi Aurea' as a synonym, and Hillier 'Sarniensis Aurea' and later U. × sarniensis 'Dicksonii'. Clibrans' nursery of Altrincham, however, described it (1922) as otherwise identical "in habit and constitution" to 'type' Cornish Elm. The Späth nursery of Berlin distributed it from c.1913 as U. campestris cornubiensis Dicksonii. The nursery Messieurs Otin père et fils of Saint-Étienne sold an Ulmus Wheatleyi aurea pyramidalis, with leaves marbled yellow, in 1882, earlier than Dickson's introduction.
Hosta sieboldiana, Siebold's plantain lily, is a species of hosta native to Japan. A putative variety, Hosta sieboldiana var. elegans, has gained the Royal Horticultural Society's Award of Garden Merit, as has a putative variety of its synonym; Hosta fortunei var. aureomarginata, the gold-edged plantain lily. The cultivars 'Blue Angel', 'Blue Mammoth', and 'Olive Bailey Langdon' have also gained the RHS Award of Garden Merit.
Eriolarynx is a genus of flowering plants in the family Solanaceae, found in Peru, Bolivia and northern Argentina. Their trumpet-shaped flowers are pollinated by hummingbirds, and to a lesser extent, bees.
