Lupinus texensis Hook.
Texas bluebonnet, Bluebonnet, Texas lupine, Buffalo clover, Wolf-flower
Fabaceae (Pea Family)
Texas lupine has larger, more sharply pointed leaves and more numerous flower heads than similar lupines. Light-green, velvety, palmately compound
leaves (usually five leaflets) are born from branching, 6-18 in. stems. These stems are topped by clusters of up to 50 fragrant, blue, pea-like flowers. The tip of the cluster is conspicuously white.
This is the species often planted by highway departments and garden clubs and is one of the six Lupinus
species which are the state flower of Texas.

Not only does the state flower of Texas bloom oceans of blue, but this famous wildflower forms attractive rosettes in winter. This is the species often used by highway departments and garden clubs. If planting this species in areas where it has not formerly grown, it may be helpful to inoculate the soil with a rhizobium
(soil-borne bacteria which form nitrogen-rich root nodules) for lupines.

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.
