Rocky Mountain Columbine

"The white and lavender Columbine, Aquilegia caerules, was adopted as the official state flower of Colorado on April 4, 1899 by an act of the General Assembly. 
In 1925, the General Assembly made it the duty of all citizens of Colorado to protect this rare species from needless destruction or waste. To further protect this fragile flower, the law prohibits digging or uprooting the flower on public lands and limits the gathering of buds, blossoms and stems to 25 in one day. 
It is unlawful to pick the columbine on private land without consent of the land owner." - Google
