Texas Bluebonnets Square Sticker

"Texas Bluebonnets" by Catherine Sherman. A field of bluebonnets blooms in spring in Nacogdoches County, Texas. In the background are yellow wildflowers and a white picket fence. Texas designated the bluebonnet as the official state flower in 1901. Bluebonnet flowers were named for the blue colour and sunbonnet-shaped petals (though not all bluebonnets are blue). Texas has also designated an official bluebonnet tartan, bluebonnet city (Ennis, Texas), bluebonnet trail (also in Ennis), bluebonnet festival (Chappell Hill Bluebonnet Festival), and bluebonnet flower song. The original 1901 legislation (Senate Concurrent Resolution No. 10, 27th Legislature) specifed Lupinus subcarnosus, but was amended in 1971 to include L. texensis and "any other variety of bluebonnet not heretofore recorded" (there are at least four other species of bluebonnet growing in Texas: L. havardii, L. concinnus, L. perennis, and L. plattensis) (L. texensis and L. subcarnosus are native to Texas).
