Lupinus havardii S. Watson
Big Bend Bluebonnet, Big Bend Lupine, Havard Bluebonnet, Chisos Bluebonnet
Fabaceae (Pea Family)
USDA Symbol: LUHA
Much taller than most bluebonnets, Big Bend or Havard bluebonnet grows 1-3 ft. high with the flowers on the upper 4-8 inches of the stem. The flowers of this winter annual are very deep blue with a lemon blotch. Palmate leaves are divided into seven leaflets.
The tall stems and showy flowers of L. havardii distinguish it from L. subcarnosus, a smaller, less showy species, which was originally designated as Texas' state flower (in 1901). In 1971, however, the state legislature designated all Lupinus species as the official state flower.

Warning: Plants in the genus Lupinus, especially the seeds, can be toxic to humans and animals if ingested. Sensitivity to a toxin varies with a personís age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plantís different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil.
