Japanese elm

Ulmus davidiana is a deciduous tree, 20 to 35 meters high. It blooms and bears fruits from February to May; the yellow-green flowers appear before the leaves.

It adapts to a wide variety of soil and pH types, but this affects its growth. It prefers a sunny exposure.
It is mostly used as ornamental tree, for timber, for heating and in violin making.

The bark has anti-inflammatory medicinal properties.

Leaves and fruits are edible. The inner bark, dried and reduced to powder, is used as a thickener in soups in Asia.

The mucilage, present in the bark, is also employed in the cosmetics industry. It serves as formation aid in forming paper sheets. This mucilage is also 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.

The bark is also used to produce threads which will give a coarse woven fabric.
