Lupinus havardii (Big bend bluebonnet)
Bransford, W.D. and Dolphia

Lupinus havardii

Lupinus havardii S. Watson

Big Bend Bluebonnet, Big Bend Lupine, Havard Bluebonnet, Chisos Bluebonnet

Fabaceae (Pea Family)



USDA Native Status: L48 (N)

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.
