Shiny Xylosma

Xylosma congesta, commonly known as shiny xylosma, is a species of flowering plant in the family Salicaceae, native to East Asia. Originally described in 1790 as Croton congestus, the species was later reassigned to Xylosma in 1919. The plant is widely grown ornamentally for its dense growth habit and shiny foliage, but its introduction to the United States as a result has led to its emergence as a potential invasive species. Other common names include dense logwood and zuo mu (Chinese: 柞木).
