The bluebonnet was made the State Flower of Texas in 1901.
Actually, the Sandyland bluebonnet was first named the state flower, but for 70 years people argued about which bluebonnet was the prettiest. In 1971, Texas officially named all varieties of bluebonnets in Texas the state flower.
This resulted in five state flowers.
- Lupinus texensis - Texas bluebonnet
- Lupinus subcarnosus - Sandyland bluebonnet
- Lupinus Havardii - Big Bend bluebonnet
- Lupinus concinnus - annual lupine
- Lupinus plattensis - dune bluebonnet
