About Euonymus hamiltonianus Wall.
In the wild, Euonymus hamiltonianus Wall. can grow as a 3-meter shrub or as a tree reaching up to 20 meters in height. Its leaf blades are somewhat oval with pointed tips, growing up to 15 centimeters long. The leaves range from leathery to papery in texture, have rough surfaces, and bear slightly wavy edges. This species produces inflorescences that are cymose clusters of several white flowers, each flower measuring nearly a centimeter across. Its fruit capsule, which can be brown, yellowish, or reddish, splits into four sections that hold brown seeds with orange arils. Like other spindle trees, this plant is cultivated as an ornamental for its bright fall foliage, which comes in many vivid shades of red, pink, and yellow; its fruits and large seeds are also considered attractive ornamental features. Known cultivars include 'Coral Charm', which has light pink fruit capsules holding seeds with red arils, and 'Red Elf', a shorter, shrubbier cultivar with dark pink fruits and seeds with orange-red arils. A number of novel chemical compounds have been isolated from Euonymus hamiltonianus, including the coumarins euonidiol and euoniside, plus several triterpenes.
