Any of several flowering plants, including the Texas bluebonnet ( Lupinus subcarnosus ), a North American annual legume native to the plains of Texas.
About 1 ft (0.3 m) tall, it bears silky-haired compound leaves and clusters of purplish blue flowers marked in the centre with white or yellow. In the spring it covers immense areas in southern and western Texas like a blue carpet. It is one of the most popular wildflower s of Texas. In Scotland the name is given to the bluebottle ( Centaurea cyanus ) and to the blue scabious, or devil's bit ( Succisa pratensis ).
