Appearance
This is an erect, branching herb sometimes exceeding one meter. Each palmate leaf is divided into 5 to 9 linear leaflets under 4 centimeters long. The herbage is slightly hairy in some areas. The inflorescence bears many flowers in shades of blue, violet, pink, or white. The fruit is a legume pod containing seeds of varying colors from dark gray to brown to white, or speckled or mottled.
Uses
It is cultivated as a food crop for its edible legume seeds and as a fodder for livestock. Like other legumes the lupine fixes nitrogen and it is planted in exhausted fields as a soil improver. Bacteria living in the rhizosphere of this lupine include the newly discovered species ''Kribbella lupini''.References:
