About
Populus lasiocarpa, the Chinese necklace poplar, is a large, deciduous tree to 20 m with the finest leaves of any poplar � ovate, to 30 cm long, with conspicuous crimson stalks and midribs. Yellow male or green female catkins to 25 cm long are produced in spring. A handsome and distinctive 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 very rapid growth as a specimen tree; useful as windbreaks. This species will tolerate most soils except those that are constantly waterlogged and in full sun. Avoid growing within 40m of buildings as the vigorous root system may damage drains and foundations, particularly on clay soils; has the potential to become a nuisance
PruningPruning group 1 in late summer to avoid bleeding from pruning cuts. Established trees need little pruning; sucker removal in autumn or winter
PropagationPropagate by hardwood cuttings in winter and from suckers in autumn or late winter
Pest resistanceMay be susceptible to leaf beetles, sawflies and caterpillars
