Tulip Poplar (Liriodendron tulipifera) is a large double trunk tree that produces numerous large, brilliant, tulip shaped flowers colored greenish yellow with dashes of red and orange. The flower's red base guides bees to abundant nectar, which is also popular with hummingbirds and is a source of gourmet honey. Hydrochlorate of tulipiferene, an alkaloid and heart stimulant, is made from the inner bark of tulip poplar roots. Its fruit is an aggregate group of samaras, seeds with wings, and in winter the upright, woody cores of the samara cones persist on branch tips after the samaras have been released. It has also been called canoe tree because Native Americans used it to make dugouts. After the Civil War, railroads accessing southern Appalachia were built and massive logging of Tulip Poplar ensued, and the wood is used for furniture, flooring, general construction, plywood, and paper pulp. It is also a host plant for Tiger Swallowtail and Tuliptree Silkmoth larva.
