The Black Mulberry Morus nigra, native to south-west Asia, was probably introduced about 1500. It has been cultivated for centuries for its edible fruit and has been planted in many cottage gardens, formal gardens and parks. The fruit of the Black Mulberry is sweet and juicy in late summer.
The White Mulberry Morus alba, native to China, was introduced to Britain in the 16th century. It is the favourite food plant of the silkworm and is cultivated on a large scale in China and other parts of the World. It is rare in Britain but is found in a few gardens in the warmer areas.
