Description

More tree-like than shrub-like. Petioles not flattened as in P. tremuloides.

The leaves of a lot of young cottonwood trees we've observed lately are shaped like this--they seem to become more triangular as the tree increases in size.

It is used for timber, and is notable as a model organism in plant biology. Its full genome sequence was published in 2006. It is the first tree species to be sequenced.
