This is one of the tallest and most beautiful of the eastern hardwoods. Also known as the yellow poplar, it has a straight trunk with a narrow crown that spreads with age. One of the largest tulip poplars in Pittsburgh can be seen in Allegheny Commons near the community college. In spring, it produces bright orange and green flowers similar to tulips. In early America, pioneers hollowed out the trunks to create canoes. The wood is also used for furniture, crates, toys, musical instruments and pulp.
