White poplars have invasive traits that enable them to spread aggressively. While these trees have demonstrated invasive traits, there is insufficient supporting research to declare them so pervasive that they cannot be recommended for any planting sites. Review of risks should be undertaken before selecting these trees for planting sites. White poplar is a large, fast-growing, relatively short-lived tree for parks, golf courses and other large landscapes. Often found growing in open, moist sites along waterways. Distinctive five-lobed, dark green leaves have a white undersurface. The mature bark is gray to white with distinguishing dark diamond shape blotches. Brittle wood is prone to storm damage.
