About
Populus wilsonii, Wilson's poplar, is a fast-growing, deciduous tree to 25 m producing leaves with very long stems that make them flutter in the wind, emerging coppery in spring then becoming dark green before turning yellow in autumn. A handsome and ornamental poplar for a large, open, moist site.
About the genus
Populus, the poplars and aspens, are mostly very fast-growing, large, deciduous trees producing male and female catkins on separate trees before the leaves open in spring. Male catkins are the more ornamental; female trees can be a nuisance from cottony, wind-blown seeds. Excellent trees for large landscapes.

Care notes
CultivationCultivated for their very rapid growth as specimen trees and useful for windbreaks. Tolerant of any soil other than constantly waterlogged soils. Avoid growing within 40m of buildings as the vigorous root systems may damage drains and foundations, particularly on clay soils. It has the potential to become a nuisance. For more advice see tree cultivation
PruningPruning group 1 in late summer to avoid bleeding from pruning cuts but established trees need little pruning. Suckers can be removed in autumn or winter
PropagationPropagate from hardwood cuttings
Pest resistanceMay be susceptible to leaf beetles, sawflies and caterpillars
Disease resistanceMay be susceptible to leaf spots, poplar bacterial canker, tree rusts and honey fungus
