Origin
Sunshine Nursery, Oklahoma, USA

The Japanese Elm Ulmus davidiana var. japonica Rehd. Nakai (formerly U. propinqua C. K. Schneid.) cultivar 'JFS-Bieberich' (Emerald Sunshine™), is a new clone from the Sunshine Nursery, Oklahoma, derived from seed collected in China by proprietor Steve Bieberich. The tree attains a height of 10 m and develops a neat vase shape, distinguished by its thickish, deep-green leaves (turning dull yellow in the fall) and stout stem. It is tolerant of high pH levels and soil compaction, and is also highly resistant to desiccating summer winds of the Plains ^[1]. The tree was summarized by Michael A. Dirr, Professor of Horticulture at the University of Georgia as "impressive" [1]. 'JFS-Bieberich' (Emerald Sunshine™) has been included in the National Elm Trial coordinated by Colorado State University. It is not known to have been introduced to Europe or Australasia.
