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 borne 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 collectively designated the state flower of Texas.
