Species | Ulmus parvifolia |
Cultivar | 'Pathfinder' |
Origin | US |
The tree is of modest proportions, rarely reaching > 11 m in height, with a crown slightly less in diameter. The leaves are a glossy yellow-green, and variously described as turning 'grayish red' or 'brilliant red' in autumn. The trunk sports the typical mottled bark.[1][2]
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[3] However, tolerance of Elm Yellows in the USA was found to be poor. [4]
'Pathfinder' is not known to be in cultivation beyond North America.
