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 genus Lupinus L. and, in particular, its North-American species, were divided by Sereno Watson (1873) into three sections: Lupinus, Platycarpos, and Lupinnelus.Differences in habitat and in the number of ovules were the basis for this classification.ubgenus Lupinus consists of 12 species from Africa and the Mediterranean, with a minimum of 4 ovules or seedbuds. The taxonomy of Lupinus has always been confusing. It is not clear how many distinct species there are or how they might be organized within the genus.
