Abstract

A Zelkova serrata variety of larger size than Zelkova serrata "Village Green", U.S. Plant Pat. No. 2,337, having vase-shaped configuration, larger leaves of paler green, turning more orange than rusty red of "Village Green", in the fall, cold hardiness at temperatures to -16 degrees F., good foliar resistance to air borne pollutants and good drought resistance in heavy clay soil.

I claim: 
     
       1. A new and distinct variety of Zelkova serrata tree, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of narrowly upright growth, terminating in a vase-shaped crown, growing much taller than Zelkova serrata "Village Green", larger leaves of paler green than "Village Green", excellent cold hardiness, surviving at temperatures as low as -16 degrees F., without trunk or branch damage, good foliar resistance to air-borne pollutants, and good drought resistance even in heavy clay soils.
