Poplars also include Quaking Aspens (Populus tremuloides) and Eastern Cottonwoods (Populus deltoides)… and while I think it would make sense to just call them all various Poplars, at least they aren’t named after a genus that is a different and completely unrelated tree family.
Even if you don’t know the scientific name, the shape of the leaves alone give some indication that it’s unrelated to Poplars. Poplar leaves are generally spade shaped with teeth, where the tulip poplar has no teeth and has a very unusual notched palm shape. In fact, I am not sure what the Tulip Poplar IS related to, if anything. It’s just a weird tree. Cool, but weird. Not unlike myself!
