The bluebonnet, a name common to several North American species of Lupinus, is the state flower of Texas. They typically grow about 0.3 m (1 ft) tall. The name is possibly derived from the shape of the petals of the flower and their resemblance to the bonnets worn by pioneer women to shield themselves from the sun.
