Euonymus /juːˈɒnɪməs/ is a genus of flowering plants in the staff vine family Celastraceae. Common names vary widely among different species and between different English-speaking countries, but include spindle (or spindle tree), burning-bush, strawberry-bush, wahoo, wintercreeper, or simply euonymus. It has about 140 species [1] [2] [3] of deciduous and evergreen shrubs, small trees and lianas. They are mostly native to East Asia, extending to the Himalayas, [4] and they are also distributed in Europe, Australasia, North America, and Madagascar. Fifty species are endemic to China. [2]
The inconspicuous flowers occur in small groups, and can be green, yellow, pink or maroon in color depending on species. [4] The leaves are opposite (rarely alternate) and simple ovoid, typically 2–15 cm long, and usually with a finely serrated margin. The fruit is a pink or white four- or five-valved pod-like berry, which splits open to reveal the fleshy-coated orange or red seeds.
The seeds are eaten by frugivorous birds, which digest the fleshy seed coat and disperse the seeds in their droppings. Many species are used in traditional medicines, and parts of the plants can be poisonous to humans. [5]
The wood of some species was traditionally used to make spindles for spinning wool; [6] this use is the origin of the British English name of the shrubs.
Euonymus are popular garden shrubs, grown for their foliage, the deciduous species often exhibiting very bright red autumnal colours, and also for the decorative berries. Euonymus alatus (winged euonymus or burning-bush) is considered an invasive species in the woodlands of the northeastern United States.
A shrub or bush is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead.
Deutzia is a genus of about 60 species of flowering plants in the family Hydrangeaceae, native to eastern and central Asia, and Central America and also Europe. By far the highest species diversity is in China, where 50 species occur.
Euonymus japonicus is a species of flowering plant in the family Celastraceae, native to Japan and Korea.
Euonymus europaeus, the spindle, European spindle, or common spindle, is a species of flowering plant in the family Celastraceae, native to much of Europe, where it inhabits the edges of forest, hedges and gentle slopes, tending to thrive on nutrient-rich, chalky and salt-poor soils. It is a deciduous shrub or small tree.
Euonymus alatus, known variously as burning bush, winged euonymus, winged spindle, and winged spindle-tree, is a species of flowering plant in the family Celastraceae, native to central and northern China, Japan, and Korea.
Euonymus atropurpureus is a species of shrub in the bittersweet family. It has the common names American wahoo, eastern wahoo, burningbush and hearts bursting with love. It is native to eastern North America.
Euonymus fortunei, the spindle, Fortune's spindle, winter creeper or wintercreeper, is a species of flowering plant in the family Celastraceae, native to east Asia, including China, Korea, the Philippines and Japan. E. fortunei is highly invasive and damaging in the United States, causing the death of trees and forest in urban areas.
Euonymus lucidus is a species of Euonymus native to the Himalaya region, from Pakistan east to northern Assam and Myanmar.
Euonymus americanus is a species of flowering plant in the family Celastraceae. Common names include strawberry bush, American strawberry bush, bursting-heart, hearts-a-bustin, and hearts-bustin'-with-love. It is native to the eastern United States, its distribution extending as far west as Texas. It has also been recorded in Ontario.
Euonymus occidentalis is a species of spindle tree known by the common names western burning bush and western wahoo.
Euonymus hamiltonianus, known by the common names Hamilton's spindletree, Himalayan spindle, and Siebold's spindle is a species of flowering plant in the family Celastraceae. It is native to Asia, where it is distributed in Afghanistan, Russia, China, Japan, Korea, India, Nepal, Pakistan, Bhutan, Thailand, and Myanmar. This is one of the most common Euonymus species. It is cultivated in gardens and landscapes in other parts of the world.
Euonymus phellomanus is a species of flowering plant in the family Celastraceae, native to China. It is one of several species within Euonymus called spindle or spindle tree. A substantial deciduous shrub growing to 2–4 m (6.6–13.1 ft) tall by 2.5 m (8.2 ft) broad, it produces insignificant yellow-green flowers in May followed by brilliant pink fruits in autumn. The fruits sometimes break open to reveal bright orange seeds. A notable feature is the rough corky bark which with age develops "wings" clothing the length of each branch. A similar effect is seen in the related Euonymus alata. This feature gives rise to a name occasionally used, the corktree.
Euonymus sachalinensis, the flat-stalked spindle, is a species of flowering plant in the family Celastraceae, native to Japan, China, Korea, and the Island of Sakhalin. Growing to 2.5 m (8.2 ft) tall and broad, it is a deciduous shrub notable for its leaves turning red in autumn, and its red fruit which splits open to reveal orange seeds. Exceptional specimens, such as the one in the Hørsholm Arboretum, Copenhagen University, can become trees up to 4 m (13 ft) in height.
Euonymus oxyphyllus, the Korean spindle tree, is a species of flowering plant in the family Celastraceae, native to central and eastern China, Manchuria, Korea, Japan and the Kurils. It is a shrub or small tree typically reaching 2.5 m (8 ft). The Royal Horticultural Society considers it to be a good tree for smaller gardens, especially for its colorful Autumn foliage and fruits.
Euonymus aculeatus, the prickly spindle, is a species of flowering plant in the family Celastraceae. It is native to southern China. A scrambling evergreen shrub reaching 2 to 3 m, it is typically found in forests and scrublands from 300 to 1,500 m above sea level. Valued for the visual appeal of its prickly orange fruit, it can be trained to climb up a garden wall, or be used as a ground cover.
Euonymus myrianthus, the many-flowered spindle, is a species of flowering plant in the family Celastraceae. It is native to central and southern China. A variable evergreen shrub or small tree, and reaching 3 to 12 m in height, it is typically found in wooded areas and forests, from near sea level up to 1,200 m (3,900 ft). In cultivation it does not grow much past 4 m (13 ft), and is valued for its profusion of yellow-orange fruit and scarlet arils which remain on the plant and provide winter interest. It is readily available from commercial suppliers.
Euonymus sanguineus, the blood red spindle, is a species of flowering plant in the family Celastraceae. It is native to Nepal, and to nearly all of China except Xinjiang, Manchuria, and Hainan. A deciduous shrub reaching 3 to 5 m, it is typically found in scrublands and mixed evergreen/deciduous forests, at elevations from 1,800 to 3,700 m. It may be available from specialty suppliers.
Euonymus wilsonii, the Chinese euonymus, is a species of flowering plant in the family Celastraceae. It is native to central and southern China. A large, lax shrub typically 3 to 4 m tall, it is found in forests and scrublands at elevations from 1,000 to 2,600 m.
Euonymus nanus, the dwarf spindle tree, is a species of flowering plant in the family Celastraceae. It is native to the Black Sea region, Central Asia, Mongolia, and northern China, and it has been introduced to Germany. A deciduous or semi-evergreen shrub reaching 1 to 2 m, it is adapted to cold, dry conditions, and is typically found in forests and scrublands high in the mountains. Available from commercial suppliers, its leaves are narrow and resemble those of rosemary.
Euonymus macropterus is a species of flowering plant in the family Celastraceae. It is native to southern Russian Far East, including Sakhalin and the Kuriles, Manchuria, the Korean peninsula, and Japan. A deciduous shrub reaching 3 m (10 ft) tall and equally wide, it is typically found in mixed evergreen/deciduous forests, and in scrublands, at elevations from 300 to 2,100 m.
