The Euonymus alatus is an evergreen shrub with seven angles. The stem is erect and thornless. The leaves are opposite; with long petioles, enlarged at the base and clasping the stem; palmately compound with 5-7 leaflets. The leaflets are elongated ovals, measuring 2-5 centimeters long and 8-15 millimeters wide. They have a gradually pointed tip, a wedge-shaped base, and serrated margins with spine-like teeth. The upper surface of the leaflets has soft teeth, while the lower surface is light green in color. The flowers are arranged in umbrella-shaped inflorescences, forming compound cone-like inflorescences. The calyx is 5-toothed and the petals are arranged in a claw-like manner. There are 5 stamens and the ovary is inferior. The fruit is flat.
The Euonymus alatus can be either a deciduous small tree or a tree, with an umbrella-shaped crown and an elegant posture. The bark is smooth and the twigs are reddish-brown. The leaves are opposite, palmately 7-9 lobed, with the base truncate to form a heart shape. The lobes have a tail-like tip and irregular sharp or heavily serrated edges. The young leaves are densely covered in soft hairs, while the old leaves are smooth and hairless. The red leaves in autumn are extremely beautiful.
