New Horizon Elm
The New Horizon elm is a product of a cross between U. pumila and U. japonica and is an introduction from the University of Wisconsin-Madison. It has many of the desirable features required for growth in the urban forest: fast growth, good insect resistance, and good DED resistance. In some cases co-dominant leaders and heavy side-branches can develop quickly on this variety, so higher levels of maintenance are required, especially in young trees. Like the Homestead elm, New Horizon appears to be favored by elm leaf beetle and has shown moderate feeding in our research plots.
