Yellow-poplar is the tallest hardwood tree in North America with one of the most perfect and straight trunks in the forest. The tree has a very unique leaf with four lobes separated by rounded notches. The showy flower is tulip-like (or lily-like) which supports the alternate name of tulip poplar. The soft and light wood was hollowed out by early American settlers to use as canoes. Today's wood is used for furniture and pallets.
