Our state flower, Texas Bluebonnet, is an upright winter annual that reaches heights of eight to sixteen inches. It’s leaves are divided into five leaflets, each being about 1 1/4 inches long. The blue flowers have a white spot on the upper petal that turns wine-red after pollination. The flowers form a spike with the uppermost flowers being white. Texas Bluebonnet can be found in gravelly, sandy, sandy-clay or calcareous soils of the Edwards Plateau and South Texas Plains. It blooms from March to May. The seeds are consumed by bobwhite quail.
