Easy · Beginner friendlyAbout Japanese Spindle Tree
Japanese Spindle is a dense upright evergreen shrub from Japan, growing 6-15 feet tall with thick glossy dark green leaves. Its dense branching and tolerance of heavy shearing make it an excellent formal hedge, topiary, and coastal screening plant. Highly salt-tolerant, it thrives in seaside gardens where most evergreens struggle. Numerous cultivars offer gold, white, and green variegated foliage. Popular throughout the American South and California for its toughness and year-round green density.

History
Euonymus japonicus is native to Japan, Korea, and China, typically occurring in coastal forests. Swedish botanist Carl Peter Thunberg described the species in 1780 in Flora Japonica. In Japan the tree is called masaki and has been planted around homes, shrines, and temples since ancient times as an evergreen hedge and protective screen—its thick leathery leaves are resistant to coastal salt spray, wind, and urban pollution.
Introduced to European cultivation around 1800 and to North America shortly after, the species became widely used in mild coastal regions (Pacific coast of the US, the Gulf Coast, Mediterranean Europe) as a formal hedging and topiary evergreen, remarkably tolerant of hard shearing and salt. Numerous variegated cultivars are popular: 'Aureus' (center-yellow), 'Aureomarginatus', 'Microphyllus Variegatus', 'Silver King', 'Silver Princess', 'Chollipo' (introduced from Korea), and 'Moness' (Green Spire). Unlike the closely related E. fortunei, E. japonicus rarely becomes invasive.
It is highly susceptible to powdery mildew and scale insects in humid climates. Introduced to Western gardens in 1804. Widely used in California and Gulf Coast gardens where its salt and heat tolerance are invaluable. The cultivar 'Green Spire' offers a narrow columnar form ideal for tight spaces.
