The mountain tailcup lupine is a vigorous perennial native to high-elevation sites in California, Nevada, and Oregon, preferring well-drained soils and partial sun. Water consistently during the growing season but avoid standing water, which can cause root rot. As a legume, it fixes atmospheric nitrogen and enriches the soil without the need for heavy fertilization.
