Ulmus parvifolia 'Pathfinder'

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.
