Silky lupine grows in northern areas from Washington and Oregon east to South Dakota. Tailcup lupine is found in Oregon, California, Idaho, Utah, Montana, and Wyoming.

The silver bush lupine descended from a variety of Lupinus species, and is among two-hundred to four-hundred species of annual and perennial species of lupine that can be found from Alaska, spanning from the northern Western Hemisphere, to Chile in South America (Ainouche and Bayer, 1999).owever, no infrageneric classification of lupines is available at this time, and it is necessary to provide a clear overview of the genus' origin. The existence of many Lupinus species has caused a major debate of where Lupinus originated: Mediterranean-African region, North America, South America, and East Asia.
