It is an evergreenshrub which grows as a vine if provided with support. As such it grows to, climbing by means of small rootlets on the stems, similar to ivy. Like ivy, it also has a sterile non-flowering juvenile climbing or creeping phase, which on reaching high enough into the crowns of trees to get more light, develops into an adult, flowering phase without climbing rootlets. The leaves are arranged in opposite pairs, elliptic to elliptic-ovate, 2–6 cm long and 1–3 cm broad, with finely serrated margins. The flowers are inconspicuous, 5 mm in diameter, with four small greenish-yellow petals. The fruit is a smooth, dehiscent capsule with reddish arils.
Varieties
There are two or three varieties:
Euonymus fortunei var. fortunei. China, Korea
Euonymus fortunei var. radicans Rehd.. Japan
Euonymus fortunei var. vegetus Rehd. Northern Japan, doubtfully distinct from var. radicans
Range
It has an extensive native range, including many parts of China, India, Indonesia, Japan, Korea, Laos, Myanmar, Philippines, Thailand, and Vietnam. It resembles Euonymus japonicus, which is also widely cultivated but is a shrub, without climbing roots. It also is related to a variety of similar species, including Euonymus theifolius, or Euonymus vagans and also a number of named "species" which are found only in cultivation and better treated as cultivars.
Cultivation
Euonymus fortunei is widely cultivated as an ornamental plant, with numerous cultivars selected for such traits as yellow, variegated and slow, dwarfed growth. It is used as a groundcover or a vine to climb walls and trees. The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:
'Emerald Gaiety'
'Emerald 'n' Gold'
'Emerald Surprise'
'Kewensis'
'Wolong Ghost'
Plants propagated from mature flowering stems always grow as non-climbing shrubs. Some popular cultivars such as 'Moon Shadow' are shrub forms. Most of the cultivated plants belong to var. radicans. It is generally considered cold hardy in USDA zones5 to 9, and is considered an invasive species in some parts of the world, notably the eastern United States and Canada.
