These Firewheel wildflowers (Gaillardia pulchella) were blooming along the road near my house on June 5, 2018 in Norman, Oklahoma, United States.
http://www.okhistory.org/publications/enc/entry.php?entry=IN006 (retrieved June 2018) says: "Dr. Doyle McCoy, an Oklahoma public school biology teacher, chose to lobby for the adoption of the Gaillardia pulchella as the state wildflower for a simple reason: it has a high tolerance of heat and arid conditions, ensuring that a majority of the state could appreciate its promotion of Oklahoma's heritage and grace for the most of the year. Sponsored in the Forty-first Legislature by state representatives Kelly Haney, a Seminole Indian artist, and Billie Floyd, the Indian blanket quickly gained popularity."
