 The state flower, the Bitterroot, was adopted in 1895 with the support of a group called the Floral Emblem Association, which formed after Montana's Women's Christian Temperance Union adopted the bitterroot as the organization's state flower.All other symbols were adopted throughout the 20th century, save for Montana's newest symbol, the state butterfly, the mourning cloak, adopted in 2001, and the state lullaby, "Montana Lullaby", adopted in 2007.The state song was not composed until 21 years after statehood, when a musical troupe led by Joseph E. Howard stopped in Butte in September 1910.
