The Carolina Lupine is native only to forest openings in the Appalachians, but it is adaptable to rich garden soils throughout the eastern United States. It is an upright, clump-forming perennial, with lemon yellow, lupine-like flowers in late spring and early summer. Seed sown indoors requires scarification and soaking to germinate.
