Euonymus maackii, also known as Maack's Spindletree, is a deciduous shrub that can reach a height of up to 10 meters. It is one of the most common species in its genus and is widely cultivated in Europe and North America. The leaves are thin and leathery or thick and papery, with a smooth surface and crenulated margins. The flowers are white and 4-merous, with lanceolate petals and ovate sepals. The fruit is a rhombic capsule with four angles and deep grooves, containing subglobose dark brown seeds partially covered by an orange aril. The roots of Euonymus maackii yield up to 6% gutta-percha, a non-elastic rubber used for electrical insulation and in the production of plastics. This versatile plant can grow in a variety of conditions, from the edges of woodlands to near sea level, and is a great addition to any garden or landscape.
