Zelkova serrata 'Green Vase' has the distinctive, broad, vase shape of the typical species but grows almost twice as fast. 'Green Vase' has all of the other desirable characteristics of the species, including a wonderful scaffold of branches for a great winter silhouette, medium-sized, dark green leaves that turn soft yellow, orange and russet in autumn. This is a fine tree for the urban landscape as it has a high tolerance for wind, pollution, drought and compacted soils. Using a cultivar such as this one is effective when a consistent avenue of trees is desired.
