Plant cultivation and use

Ulmus parvifolia is a deciduous tree up to 25 m in height. The pale yellow flowers appear in September. They produce samaras, ripe in October, which contain seeds. It prefers moist, well-drained soils, a sun exposure. It is resistant to low temperatures.

Chinese Elm is often used as an ornamental tree or for bonsais. Its very hard wood is used in making furniture and tools.

The leaves, bark and flowers have medicinal properties. Its leaves and fruits are edible. The inner bark dried and reduced to powder is used as a thickener in soups in Asia.

The mucilage extracted from the bark is used as formation aid in paper making. This viscous material is added to the pulp to increase its viscosity and thus delay the settling of fibers in the tank. In addition, the mucilage allows a better dispersion of the long fibers.

China:

It is frequently used beside Hibiscus manihot.

Its use is mentionned in "Wuli xiaoshi" or "Some Knowledge of Physics" written by Fang Yishi in 1643.

Korea:

Its bark has been used to produce formation aid in Korea until mid 19th century.
