Urban trees are always in demand. They must be drought and pollution tolerant, quick growing, and fill a niche. One such niche is under power lines. Zelkova serrata ‘JFS-KW1′ sold as City Sprite is a tree that fulfills all of these needs and is proving to be an outstanding performer at the JC Raulston Arboretum. This tree has put on a very full crown in a very short amount of time and has developed a nice, straight trunk. Plants are extremely uniform and the relatively small (to about 25′ tall by 20’ wide) size makes it ideal for many situations. Color is bright green all summer, typically lighter than other zelkovas. Fall color is variable but can be a very nice burgundy to red.
