Euonymus japonicus 'Emerald Gem' (Emerald Gem Euonymus, similera to buxus), family Celastraceae, is a compact, evergreen shrub valued for its dense growth and glossy, dark green foliage. It typically grows around 0.6–1 m tall and wide, forming a neat, rounded mound that is well suited to low hedging, borders, and formal garden structure. Originating from Japan and Korea as part of the species Euonymus japonicus, this cultivar is widely used in ornamental landscaping for its reliability and tidy habit. Growth rate is moderate, establishing steadily and maintaining a naturally compact shape with minimal pruning. It produces small, inconspicuous greenish flowers in late spring to summer, though it is primarily grown for its foliage rather than its blooms. It prefers full sun to partial shade, adapts to a wide range of soils provided they are well-drained, and is tolerant of wind, coastal conditions, and light frost once established.
