Euonymus lanceifoliusEuonymus nikoensisEuonymus sieboldianusEuonymus yedoensisEuonymus bungeanum (misspelling)[1] Euonymus hamiltonianus, known by the common names Hamilton's spindletree,[2] Himalayan spindle,[3] and Siebold's spindle[4] 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.

[5] Like some other spindles, this plant is cultivated as an ornamental for its fall foliage, which can be many bright shades of red, pink, and yellow.

Cultivars include 'Coral Charm', which has light pink fruit capsules containing seeds with red arils, and 'Red Elf', a shrubbier breed with dark pink fruits and seeds with orange-red arils.

[8] A number of novel chemical compounds have been isolated from this plant, including the coumarins euonidiol and euoniside[9] and several triterpenes.
