Summary of InvasivenessTop of page
M. alba is a multipurpose tree widely planted in tropical, subtropical and mild temperate regions of the world for fodder and silkworm rearing, and for fruit and timber production (Gupta, 1993). Introduced M. alba has been found to be associated with invasion events in Oregon and Virgina (USA) and South Africa (Haysom and Murphy, 2003). It is also recorded as invasive in Brazil (Instituto Horus, 2011).

Notes on Taxonomy and NomenclatureTop of page
The genus Morus (family Moraceae) contains about 10 species (Parker, 1956). Many cultivars have been developed over the long period of time that Morus spp. have been cultivated for leaf and fruit production (Gerasopoulos and Stavroulakis, 1997). For example, there are about 700 cultivars in Japan that are used for rearing silkworms. There has been confusion regarding the characteristics of M. alba at various times (Watt, 1972).
DescriptionTop of page
A small to medium tree growing up to 15 m, M. alba has a short trunk, and a rounded crown with a dense canopy of spreading branches. Leaves are alternate, simple, 6-18 cm long, 5-13 cm wide, broadly ovate, dentate or lobed with 3 prominent veins running from the rounded or obliquely cordate base. Somewhat polymorphic, leaves are shiny green on the adaxial surface, paler and slightly hairy underneath. Bark is light brown to grey, smooth but may be furrowed. Dioecious, male inflorescences are small with 4 stamens, filaments inflexed in bud, green and borne on long catkins. Female flowers are inconspicuous, perianth with 4 free or almost free segments, aggregated in short spikes. Fruit is an ovoid or cylindrical syncarp composed of achenes, pendunculate, red when immature, blackish-purple, purple or greenish-white when mature, 1-2.5 cm long (Global Invasive Species Database, 2016; Tutin, 1964).
Two botanical varieties of M. alba are recognized (Zhou and Gilbert 2003): varieties ‘alba’ and ‘multicaulis’. The leaf blade of ‘alba’ is 5-15 cm, fruits are ovoid to ellipsoid, blackish purple when mature. The leaf blade of var. ‘multicaulis’ is <30 cm with cylindric fruits which are greenish-white to purple when mature.
DistributionTop of page
M. alba is native to central and eastern China, and is widely cultivated and naturalized elsewhere across the world, largely due to sericulture. In some areas M. alba is invasive, hybridizing with native species M. rubra in North America and outcompeting other native species in South Africa.

Habitat ListTop of page
Biology and EcologyTop of page
M. alba is a rapidly growing deciduous woody perennial with a deep root system. Mulberry trees are either dioecious or monoecious, and a tree sometimes will change from one sex to another. High temperatures, strong light and long days favour maleness in mulberries, with their opposites, as well as high humidity, favouring the production of female flowers. Flowers appear as cylindrical catkins along with the leaves axillary on the current season’s shoots and on spurs on older wood. Pollination is not usually a problem because mulberries are wind pollinated, and some plants will set fruit without any pollination whatsoever. In China, M. alba flowers in April to May with fruiting during May to August.
White mulberry is grown in cool temperate steppe to warm to tropical, very dry to moist, forest life zones and can be grown in annual temperatures ranging from 6-28°C (Duke, 1983). It is the most cold hardy of the mulberry species grown for their fruit, though cold hardiness varies from clone to clone. The clone ‘Tartarica’ is tolerant of temperatures down to -32°C. M. alba prefers moist, well drained loamy soils in a sunny position. However, it will grow in coarse, medium and fine soils, has some shade tolerance and is moderately tolerant of drought. Once established, it is tolerant of drought (Duke, 1983) and of saline conditions (Global Invasive Species Database, 2016). It is liable to wind damage, but in India it is cultivated up to 3300 m in altitude (Duke, 1983).

UsesTop of page
Worldwide M. alba is mainly cultivated for sericulture. China has over 400,000 ha planted for their leaves as silkworm fodder. Leaves are also used as fodder for ruminant animals and have even been eaten as a vegetable by humans. The bark can be used for paper. Ripe fruits are eaten fresh, used in desserts and cooking in pies and tarts, and also for cordials and jams. In Asia, southern Europe and southern parts of the USA, M. alba has been used for windbreaks, in landscaping, and their low water requirements and resistance to pruning makes them suitable for use as a street tree. In India the wood is used for cabinet work and sporting goods (Sánchez, 2002).
