Ulmus davidiana, also known as the David elm, or Father David elm (named after the botanist Armand David, who collected specimens), is a small deciduous tree widely distributed across China, Mongolia, Korea, Siberia, and Japan, where it is found in wetlands along streams at elevations of 2000–2300 m (6,500–7,500 ft).
[8] Ulmus davidiana is considered to have a remarkable resemblance to the American elm (U. americana) in all but ultimate size.
Its bark remains smooth for a comparatively long time, before becoming longitudinally fissured.
[16] [6] The tree was briefly propagated and marketed by the Hillier & Sons nursery, Winchester, Hampshire from 1971 to 1977, during which time only four were sold.
Additional observation shows that at least 50% of emerging leaves on the trees survived a hard freeze that lasted 5 days during April 2007.
The UK TROBI Champion is a relatively young tree at White House Farm, Ivy Hatch, Kent, measuring 5 m high by 17 cm d.b.h.
