Etymology: The name is a plain compound of "blue" and "bonnet," and the bonnet in question is the flower's shape rather than a hat. The lupine species that carpets Texas roadsides in spring has blossoms that cluster on a tall stem, and the upper petals fold back over the flower like the brim of a bonnet, a traditional hat tied under the chin. Its blue flowers, with their pale centres, complete the picture. Texans adopted the name for the state flower, and it has since been applied to several blue-flowered lupines across the southern United States. The word is written as one word today, though older sources sometimes separate it as "blue bonnet," which shows the compound was still settling into a single form.
