This plant is native to Minnesota and blooms in the spring. The seeds of the wild lupine are piousness.
Wild lupine is currently threatened or no longer present in much of its original habitat. One main reason for the decline in wild lupine is habitat destruction. Man has ripped up many of the fields where the lupine used to grow for agriculture use or urban sprawl.
Another reason for the decline is because of man made fire suppression. Fields that are destroyed by fire are cleared of most of their brush. This allows perennials like lupine to reestablish itself. If the fields are not regularly cleared, because man extinguishes wild fires, then other more evasive plants and shrubs will take over and eventually the lupine will die because it will not receive enough sunlight.
Wild lupine is an early source of food for many different insects. Chief among these is the Karner blue butterfly. The karner blue larva will only eat wild lupine. This dependence on this declining plant has endangered this butterfly, who's numbers have declined by 99 percent.
