On the other hand, the Penngift Crownvetch plant is planted at all state roads due to its aesthetic qualities and was given recognition in 1982. Both plants play important roles, while one is recognized as the state flower, the other is recognized as the beautification and conservation plant.

The Road to Recognition

Governor Gifford had to make a choice between the two bills that were passed by the state legislature that proposed either the mountain laurel or the pink azalea flower to be the official state flower. Pennsylvanians in support of any of the two flowers had been engaged in intense lobbying, forcing the governor to settle the debate. On May 5, 1933, he chose the mountain laurel over the pink azalea by signing the bill into law and effectively making it the state flower. The designation, however, did not give it special protection over other wild plants.
