Nebraska was the first state to observe Arbor Day. It was also the first to adopt a state grass. Little bluestem was given the title on May 5, 1969. Since then, at least thirteen more states have adopted official grasses. State grasses have also been proposed for Idaho, Oregon, California, and Arizona.
Most state grasses are species that provide good forage for cattle.
Indian ricegrass was sometimes eaten by Native Americans when their corn crops failed. They made bread from flour made of ricegrass seeds. Many state flowers and birds were promoted by women's clubs. Many other state birds and other symbols were selected by school children. Agricultural and conservation organizations promoted most state grasses.
