Willows, also called sallows and osiers, of the genus Salix, comprise around 350 species of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions.
Hibiscus syriacus is a species of flowering plant in the mallow family, Malvaceae. It is native to areas of east Asia, but widely introduced elsewhere, including much of Europe and North America. It was given the epithet syriacus because it had been collected from gardens in Syria. Common names include the rose of Sharon,, Syrian ketmia, shrub althea (or simply althea), and rose mallow. It is the national flower of South Korea and is mentioned in the South Korean national anthem.
Salix alba, the white willow, is a species of willow native to Europe and western and central Asia. The name derives from the white tone to the undersides of the leaves.
Salix caprea, known as goat willow, pussy willow or great sallow, is a common species of willow native to Europe and western and central Asia.
Salix purpurea, the purple willow, purpleosier willow, or purple osier, is a species of willow native to most of Europe and western Asia north to the British Isles, Poland, and the Baltic States.
Salix × fragilis, with the common names crack willow and brittle willow, is a hybrid species of willow native to Europe and Western Asia. It is native to riparian habitats, usually found growing beside rivers and streams, and in marshes and water meadow channels. It is a hybrid between Salix euxina and Salix alba, and is very variable, with forms linking both parents.
Salix viminalis, the basket willow, common osier or osier, is a species of willow native to Europe, Western Asia, and the Himalayas.
Salix babylonica is a species of willow native to dry areas of northern China, but cultivated for millennia elsewhere in Asia, being traded along the Silk Road to southwest Asia and Europe.
Fasciation, also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem, which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus producing flattened, ribbon-like, crested, or elaborately contorted tissue. Fasciation may also cause plant parts to increase in weight and volume in some instances. The phenomenon may occur in the stem, root, fruit, or flower head.
Magnolia salicifolia, also known as willow-leafed magnolia or anise magnolia, originates from Japan. It is a small deciduous tree 7.5 m (25 ft) tall, with narrow lanceolate leaves with whitened undersides. The leaves are not as narrow as true willows (Salix), but is narrow compared to other magnolias, giving this tree a finer texture. The 10 cm-wide scented flowers emerge in early spring before the leaves. Flowers have six petals. The leaves and bark are fragrant when crushed. It grows in rocky, granite soil along stream banks.
Mentha arvensis, the corn mint, field mint, or wild mint, is a species of flowering plant in the mint family Lamiaceae. It has a circumboreal distribution, being native to the temperate regions of Europe and western and central Asia, east to the Himalaya and eastern Siberia, and North America. Mentha canadensis, the related species, is also included in Mentha arvensis by some authors as two varieties, M. arvensis var. glabrata Fernald and M. arvensis var. piperascens Malinv. ex L. H. Bailey.
Salix reticulata, the net-leaved willow, or snow willow, is a dwarf willow, native to the colder parts of Europe, North America, and Northern Asia. It is found in the western United States, including the Sierra Nevada and Rocky Mountains. In Europe it extends south through the Carpathian Mountains and Alps to the Pyrenees and the mountains of Bulgaria and North Macedonia. It is common in Canada, Greenland and Finland, and present but rare in Scotland.
Salix integra is a species of willow native to north-eastern China, Japan, Korea and the far south-eastern Russia.
The Japanese elm cultivar Ulmus davidianavar.japonica 'Prospector' was originally treated as a cultivar of Wilson's elm U. wilsonianaSchneid., a species sunk as Ulmus davidiana var. japonica by Fu. A U.S. National Arboretum introduction, it was selected in 1975 from a batch of 1965 seedlings in Delaware, Ohio, and released without patent restrictions in 1990. 'Prospector' proved moderately successful in the US National Elm Trial, averaging a survival rate of 76% overall.
Ulmus 'Patriot' is a hybrid cultivar raised by the United States National Arboretum in 1980. Derived from a crossing of the American hybrid 'Urban' with the Wilson's Elm cultivar 'Prospector', 'Patriot' was released to commerce, free of patent restrictions, in 1993. Tested in the US National Elm Trial coordinated by Colorado State University, 'Patriot' averaged a survival rate of 85% after 10 years.
Reynoutria sachalinensis is a species of Fallopia native to northeastern Asia in northern Japan and the far east of Russia.
Salix triandra, with the common names almond willow, almond-leaved willow or black maul willow, is a species of willow native to Europe and Western and Central Asia. It is found from south-eastern England east to Lake Baikal, and south to Spain and the Mediterranean east to the Caucasus, and the Alborz Mountains. It usually grows in riparian habitats, on river and stream banks, and in wetlands.
Salix geyeriana is a species of willow known by the common names Geyer's willow, Geyer willow and silver willow. The type specimen was collected by the botanist Karl Andreas Geyer, for whom it was named. Its conspicuous, yellow flowers begin to bloom as early as March, to as late as the end of June.
The hybrid elm cultivar Ulmus × hollandica 'Viminalis' [:osier-leaved] was listed by the Späth nursery of Berlin as Ulmus scabraMill. var. viminalis in 1890 and as Ulmus montana viminalis from 1892. Though Späth's catalogues stated that it was "also distributed under the name planera aquatica", it remained in his lists under 'elm' and was accessioned by the Dominion Arboretum, Ottawa, and by the Royal Botanic Garden Edinburgh as an elm cultivar. A similar misidentification occurred in the mid-20th century, when the Siberian elm cultivar Ulmus pumila 'Poort Bulten' was for many years commercially propagated under the name Planera aquatica or 'water elm'. As the leaves of osier or Salix viminalis, however, differ markedly from those of Planera aquatica, being long, thin and tapering at both ends, Spath's name 'Viminalis' for this elm cultivar confirms that its leaves were not Planera-like. The probable explanation for the early distribution name is that Planera was the old name for Zelkova, a close relative of elm with willow-like leaves. It is therefore unlikely that 'Viminalis' was related in any way to the 19th-century elm cultivar Ulmus 'Planeroides'.
Salix caspica is a plant from the willow genus (Salix) within the willow family (Salicaceae). The natural range extends from eastern European Russia to far western China.
