The peony was chosen by the Indiana General Assembly as the State flower in 1957. Prior to 1957, however, two separate General Assemblies had chosen the carnation and the zinnia as the State flower. The State bird is the cardinal, and its designation has remained unchanged by the General Assembly since 1933.
Male cardinals are bright red, while female cardinals are brownish.
Both have a crest and are fond of sunflower seeds. They do not migrate south in cold weather. In 1971, Indiana adopted limestone as its State stone. Indiana is famous for its limestone, which has been used to build such famous buildings as the Empire State Building and the Pentagon. The tulip tree was chosen in 1931 as the State tree.
