Morus indica 'Unryo'

Contorted Mulberry is typically grown for its twisted corkscrew branches ('Unyro' is Japanese for twisted). It is a vigorous plant in areas with hot summers, reaching a mature height of 32 feet, with a spectacular form. However, it can be pruned to a smaller tree or shrub. 'Unyro' is perhaps among the most popular contorted cultivars of woody plants. In addition to its twisted form, 'Unryo' features large, unlobed leaves and is a female clone although fruit set is rare.

Contorted Mulberry does well in loamy, well-drained soils, in full sun or partial shade. It will tolerate a variety of soils including clay. Mulberry roots are brittle and care should be taken with planting them. Prune if needed in winter when the plant is fully dormant to prevent running sap. Prune only badly placed branches and dead wood.

'Unyro' is sometimes sold under different names and there is some controversy whether Contorted Mulberry belongs to M. alba or M. indica. Most tradespeople lean toward M. indica. To confuse things even more, the cultivar is sold in North America as 'Unyro', but sold as 'Spirata' in Europe.

Some recommend siting the plant by itself to highlight the twisted form and the branches and stems can be used in flower arrangements, floral displays and decoration. After leaf drop in fall, the contorted stems add excellent winter interest to the landscape.
