Morus, a genus of flowering plants in the family Moraceae, consists of diverse species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the plant has three main species ostensibly named for the fruit color of the best-known cultivar: white, red, and black mulberry (Morus alba, rubra, and nigra, respectively), with numerous cultivars, but more than 200 species are identified in taxonomy. The name “white mulberry” came about because the first specimens named by European taxonomists were a cultivated mutation prized for their white fruit, but wild trees bear black fruit like other mulberries. White mulberry is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. It is regarded as an invasive species in Brazil and the United States.
