Very likely. Poplar is the name of over 35 different varieties of trees in the willow, cottonwood and aspen families
Genes: Pupulus.

Poplar lumber can be bought at Home Depot right next to Oak and Cedar. It is sold as a fine stain grade wood. It is not in fact Poplar but comes from a tree of the Liriodendron genes and is not in fact even related to the poplar. How it got called Poplar I have no idea.
