Wild Prairie Rose
Adopted on May 5, 1897.
The Iowa Legislature designated the

was chosen for the honor because it was
one of the decorations used on the
silver service which the state presented
to the battleship USS Iowa that same
year. Although no particular species of
the flower was designated by the
Legislature, the Wild Prairie Rose (Rosa
Pratincola) is most often cited as the
