Euonymus planipes), the flat-stalked spindle, is a species of flowering plant in the family Celastraceae, native to Japan, China, Korea, and the Island of Sakhalin (whence the specific epithet sachalinensis).

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.

[2] Exceptional specimens, such as the one in the Hørsholm Arboretum, Copenhagen University, can become trees up to 4 m (13 ft) in height.

[3] This plant is cultivated as an ornamental subject.

The cultivar 'Sancho' which is more free-flowering than its parent, is a recipient of the Royal Horticultural Society's Award of Garden Merit.
