Euonymus /jˈɒnɪməs/ 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]

Description

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.

Viburnum is a genus of about 150–175 species of flowering plants in the moschatel family, Adoxaceae. Its current classification is based on molecular phylogeny. It was previously included in the honeysuckle family Caprifoliaceae.

<span class="mw-page-title-main">Privet</span> Genus of flowering plants in the family Oleaceae

A privet is a flowering plant in the genus Ligustrum. The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species, Ligustrum australianum, extends as a native into Queensland. Some species have become widely naturalized or invasive where introduced. Privet was originally the name for the European semi-evergreen shrub Ligustrum vulgare, and later also for the more reliably evergreen Ligustrum ovalifolium and its hybrid Ligustrum × ibolium used extensively for privacy hedging, though now the name is applied to all members of the genus. The generic name was applied by Pliny the Elder to L. vulgare. It is often suggested that the name privet is related to private, but the OED states that there is no evidence to support this.

<i>Euonymus hamiltonianus</i> Species of flowering plant

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.

<i>Euonymus phellomanus</i> Species of flowering plant

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.

<i>Euonymus sachalinensis</i> Species of flowering plant

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.

<i>Euonymus oxyphyllus</i> Species of plant in the genus Euonymus

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.

<i>Euonymus myrianthus</i> Species of plant

Euonymus myrianthus, the many-flowered spindle, is a species of flowering plant in the family Celastraceae. It is native to central and southern China.

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.

<i>Euonymus sanguineus</i> Species of plant

Euonymus sanguineus, the blood red spindle, is a species of flowering plant in the family Celastraceae. It is native to Nepal, and nearly all of China except Xinjiang, Manchuria, and Hainan.
