Are you ready to learn a little secret about the Texas state flower? It is more accurately state flowers (plural) because the Lone Star State has five, and they are all bluebonnets.


In 1901, the Texas Legislature decided the state needed an official designated flower. Three candidates were in line to claim the title: the prickly pear, the cotton boll, and the bluebonnet. A women’s group in attendance that day threw its support behind the bluebonnet, also known as the sandyland bluebonnet, Lupinus subcarnosus. This variety of native bluebonnet is a lovely royal blue and grows primarily along the Texas coast and in the southern, sandier part of the state. 
The biggest problem was that no one in the Legislature knew what a bluebonnet looked like. The women brought in a painting by Mode Walker, “Bluebonnets and Evening Primrose,” which knocked the other two out of contention. On March 7, 1901, the sandyland bluebonnet became the first official state flower of Texas.


Once the sandyland bluebonnet was official, the grumbling began. Texas is a big, bold state, and many folks were not happy that the state flower represented only a portion of it. From 1901 to 1971, opinions were expressed and suggestions were made encouraging legislators to revisit the choice with a push for a statewide favorite, Lupinus texensis, popularly thought of as THE Texas bluebonnet. This is likely the variety of bluebonnet you know and love in the Hill Country of Central Texas. It has a bigger, bolder blue stalk of flowers topped off with a noticeable white tip. This bluebonnet is found naturally just about anywhere in the state.
Hoping to solve its bluebonnet blues for good, on March 8, 1971, the Texas Legislature opted “to include the Lupinus texensis and any other variety of bluebonnet not heretofore recorded along with the Lupinus subcarnosus for recognition as the official state flower of Texas.” In doing so, not only did Texas get one additional state flower, it got four additional state flowers for a total of five all-native bluebonnets. However, only L. subcarnosus and L. texensis, are endemic to the state, which means they are only found naturally in Texas.
