?
The tulip tree, Magnoliaceae Liriodendron tulipifera, known also as yellow poplar, was adopted by the 1931 General Assembly (Indiana Code 1-2-7). It attains great height and can be found throughout the state. The leaf is distinctive (it appears in the border of the state seal), and the lovely bell-shaped greenish-yellow flowers appear in May or June. The soft white wood has many uses.

Yellow-poplar (Liriodendron tulipifera), also called tuliptree, tulip-poplar, white-poplar, and whitewood, is one of the most attractive and tallest of eastern hardwoods. It is fast growing and may reach 300 years of age on deep, rich, well-drained soils of forest coves and lower mountain slopes. The wood has high commercial value because of its versatility and as a substitute for increasingly scarce softwoods in furniture and framing construction. Yellow-poplar is also valued as a honey tree, a source of wildlife food, and a shade tree for large areas.

-
Leaf: Alternate, simple, palmately veined, orbicular, 4-lobed with an entire margin, 4 to 8 inches long. Somewhat shaped like a tulip.

-
Twig: Red-brown in color, often with a shiny appearance or a waxy bloom. Stipules are large and encircle the twig. Buds are elongated and valvate, resembling a "duck bill". Twigs have a sweet, spicy odor when broken.
