Abstract
An attractive male Green Ash tree is provided that exhibits extreme winter hardiness. An oval crown is formed that tends to be denser and more compact than that of the ‘Patmore’ variety (U.S. Plant Pat. No. 4,684). The branch angles generally are greater than those of the ‘Patmore’ variety. The leaflets are glossy dark green and generally display less serration than the ‘Patmore’ variety. Also, the bark generally is smoother than that of the ‘Patmore’ variety particularly when young. The new variety is well suited for growing as a street planting or an ornamental shade tree in the landscape.
