Texas Bluebonnet

  • by

Texas Bluebonnet (Lupinus texensis)

Description: 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.

Family: Fabaceae

Bloom Notes: 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.
