Texas Bluebonnet

The name Texas bluebonnet blossoms resemble the bonnets of pioneer women. Bluebonnets are also known by the name buffalo clover, wolf flower & Texas lupine.

There are 5 different varieties of Lupinus: L. subcarnosus, L. texensis, L. Havardi, L. concinnus, and L. plattensis. However, L. texensis, or Texas bluebonnet, is the most widely spread in Texas and produces various shades of blue blossoms. Whereas you will find L. Havardi in the Big Bend part of the state and L. subcarnosus in southern and coastal Texas.
